Minecraft Launcher Error: Couldn't Load Launche...

Upon launching the game, some users are faced with an error message stating "Couldn't load launcher core from C:\Users\User\AppData\Local\Packages\Microsoft.4297127D64EC6_8wekyb3d8bbwe\LocalCache\Local\game\launcher.dll: LoadErrorNotPresent"

Minecraft Launcher Error: Couldn't load launche...

Keep getting the error "Couldn't load launcher core from C:\Program Files(x86)\Minecraft Launcher\game\launcher.dll: LoadErrorNotPresent" and then "Unable to start Minecraft Runtime Environment. This is most likely caused by corruption. Please try to reinstall Minecraft."

If nothing has worked in restoring Minecraft so far, you may need to reinstall the game. This can be done after uninstalling it first and then re-downloading the launcher from the official website. Make sure that you know your login information before attempting this method! You will need it to authorize your account and download Minecraft again.

Consider feeding the Minecraft launcher what it's asking for before you implement any other fixes. As the error window indicates, the file content on the disk is different from what the launcher expected, so downloading and manually adding the requested file may resolve the issue.

Upon replacing the file, restart the launcher to verify that the error has been resolved. If not, unzip the downloaded file in the same folder you pasted it in earlier. If the error persists, let the copied file be placed in the directory and implement the below fixes.

Microsoft Defender's Firewall could also be causing this error as it can prevent the launcher from downloading the files correctly. Therefore, whitelisting Minecraft in the Firewall settings (allowing the app through the Firewall) holds a good chance of resolving the issue.

If you wish, you can also disable the Microsoft Defender Firewall temporarily. Try running the launcher again to see if it downloads the file this time. If the error persists, reinstalling Minecraft is the best option.

If the issue persists, your last resort is to reinstall Minecraft. To do this, you must navigate to the Control Panel and uninstall the launcher. Then, you simply download your desired Minecraft version.

Perhaps, there is a bug in the launcher that affects its file downloading capabilities. Moreover, the Minecraft launcher struggles seem to get worse when the internet connection being used is slow. If you encounter too much trouble while trying to fetch updates through the Minecraft launcher, then you might be better off downloading the Minecraft executable from the website directly instead of waiting for the launcher to do the job for you.

I have Minecraft 1.12.2. Why does the Wurst MC 1.12 installer say that it couldn't find my Minecraft installation?You need Minecraft 1.12, not 1.12.2. Open the Minecraft launcher, create a profile using "release 1.12" and launch it once. Then the installer will work.

I have Minecraft 1.8.9. Why does the Wurst MC 1.8 installer say that it couldn't find my Minecraft installation?You need Minecraft 1.8, not 1.8.9. Open the Minecraft launcher, create a profile using "release 1.8" and launch it once. Then the installer will work.

We have listed down a number of different solutions for you to try out. Start with the first one and work your way down accordingly.\r\nSolution 1: Disabling Full-Screen Optimization\r\nRecent releases of Windows 10 include a feature for people who game. This feature is named \u201cFull-screen optimization\u201d and when it is enabled, it allows the operating system to optimize the video quality and performance when the games are running in full-screen mode. However, despite it doing any good, this feature is known to cause problems with the computer. You will get the error condition under discussion with slight intervals. We can disable this and see if the problem is solved.\r\n\r\n \tLocate the executable file of your game or your launcher. You can right-click on the executable and select \u201cOpen file location\u201d.\r\n \tOnce you are in the directory of the executable, right-click on it and select \u201cProperties\u201d.\r\n\r\n\r\n\r\n \tNavigate to the Compatibility tab and check the option \u201cDisable fullscreen optimization\u201d. Press Apply to save changes and exit.\r\n\r\n\r\n\r\n \tNow launch the application again using the same exe file and check if the problem got solved.\r\n\r\nSolution 2: Changing Resolution\r\nThis workaround targets the very dialogue of the error message. The message says that the computer failed to switch to the monitor resolution. We will change the resolution of your Windows and then try launching the game. This will, in turn, prompt the game to launch in the set resolution and hopefully, solve the problem.\r\n\r\n \tRight-click anywhere on your Desktop and select \u201cDisplay Settings\u201d.\r\n\r\n\r\n\r\n \tNow select a lower resolution other than the one already set.\r\n\r\n\r\n\r\n \tSave changes and exit. Now try launching your game and see if the problem got solved.\r\n\r\nSolution 3: Deleting \u2018options.txt\u2019\r\nAnother workaround which seems to work is to delete the file \u2018options.txt\u2019 from your game directory. This file is usually present in games like Minecraft. It is a file which stores all the options which are changeable in the game. It can be edited with any text editor but, if we delete it, the application will detect the file as missing and will recreate a default one. This solution will work if your file is corrupt and is causing the error message.\r\n\r\n \tNavigate to the directory of your game. It will most probably be something like \u201c%APPDATA%\\.minecraft\u201d.\r\n\r\n\r\n\r\n \tOnce in the directory, locate the file \u201coptions.txt\u201d and delete it. Now restart your computer and launch the game. The game might take an additional minute or two when it is loading the default configurations.\r\n \tNow check if the error message still persists.\r\n\r\nTip: Instead of deleting the file, you can \u2018cut-paste\u2019 it to some other directory so you can replace it back if something goes wrong.\r\n\r\nYou can also try modifying the lines to this:\r\ngraphicsfullscreen=True\r\n\r\ngraphicsheight=1080\r\n\r\ngraphicsquality=1\r\n\r\ngraphicswidth=1920\r\nMake sure that you match the width and height to match your current Windows resolution.\r\nSolution 4: Resetting Game Options (Blizzard)\r\nIf all the above methods don\u2019t work for your Blizzard game, you can try resetting the game settings using the Blizzard application. Then you can perform solution 1 on the application and hopefully, it will be solved. This problem occurs in the new Windows 10 build according to Official Blizzard support and is supposed to be fixed using this method.\r\n\r\n \tLaunch the Blizzard application. Click the Blizzard logo and click Settings.\r\n\r\n\r\n\r\n \tNow click \u201cGame Settings\u201d from the left navigation pane and click Reset In-Game Options underneath the tab of the game in which you are experiencing the error message. Press Done after making the changes and exit.\r\n\r\n\r\n\r\n \tNow within the Blizzard application, select the Hearthstone tab and select Options. Now drop down to the option \u201cOpen in Explorer\u201d and open the Hearthstone folder. Now right-click on exe and click Properties. Select the Compatibility tab and check the option Disable fullscreen optimization. Press Apply and exit (this is the same step as solution 1).\r\n \tRestart your computer and check if the problem at hand got solved.\r\n\r\nSolution 5: Selective Startup\r\nIt is a known fact that there are several startup programs which hinder the many games and causes certain errors to take place. The best way to solve this problem is to disable those startup programs.\r\n\r\n \tPress Windows + R, type \u201cmsconfig\u201d in the dialogue box and press Enter.\r\n \tOnce in the settings, select \u201cselective startup\u201d and uncheck the option \u201cLoad startup items\u201d. Press OK to save changes and exit.\r\n\r\n\r\n\r\n \tNavigate to the Services tab present at the top of the screen. Check the line which says \u201cHide all Microsoft services\u201d. Once you click this, all Microsoft related services will be invisible leaving behind all the third-party services.\r\n \tNow click the \u201cDisable all\u201d button present at the near bottom at the left side of the window. All the third-party services will now be disabled.\r\n \tClick Apply to save changes and exit.\r\n\r\n\r\n\r\n \tNow navigate to the Startup tab and click the option of \u201cOpen Task Manager\u201d. You will be redirected to the task manager where all the applications\/services which run when your computer starts will be listed.\r\n\r\n\r\n\r\n \tSelect each service one by one and click \u201cDisable\u201d at the bottom right side of the window.\r\n\r\n\r\n\r\n \tNow restart your computer and check if the error condition still persists. If the error message goes away and you are able to play your game without any problems, it means that there was either a service or an application which was causing the problem. Enable a chunk of these and check again. If the problem comes again when you enable a chunk, you would know who the culprit is.\r\n\r\nFinal Solution: Updating Graphics Drivers\r\nIf all the above methods fail, it probably means that there is a problem with the current drivers installed on your computer. If you have corrupt or outdated drivers, it may be the reason why your game fails to switch to your computer\u2019s default resolution. Now there are two ways through which you can update the drivers: either manually or automatically. In manually, you have to personally download the driver after searching for it at the manufacturer\u2019s website.\r\n\r\nBefore updating drivers, we will check if installing the default drivers solve the problem for us.\r\n\r\n \tBoot into Safe mode. Type \u201cdevmgmt.msc\u201d in the dialogue box and press Enter. Here navigate to Display Adapters, right-click on your adapter and select Uninstall Device.\r\n\r\n\r\n\r\n \tBoot your computer into normal mode, press Windows + R, type \u201cdevmgmt.msc\u201d in the dialogue box and press Enter. Most probably the default drivers will be installed. If not, right-click on any empty space and select \u201cScan for hardware changes\u201d. Now check if the game works without any problems. If it does without any problems, good for you. If it doesn\u2019t, carry on.\r\n \tNow there are two options. Either you can search online for the latest driver available for your hardware from the manufacturer\u2019s website such as NVIDIA etc. (and install manually) or you can let Windows install the latest version itself (search for updates automatically).\r\n \tWe will take a look at installing manually. Right-click on your hardware and select \u201cUpdate driver\u201d. Select the first option \u201cSearch automatically for updated driver software\u201d. Choose the second option if you are updating manually and select \u201cBrowse for driver\u201d and navigate to the location where you downloaded.\r\n\r\n\r\n\r\n \tRestart your computer after installing the drivers, launch the game and check if this solves the problem.\r\n","publisher":"@id":"#Publisher","@type":"Organization","name":"Appuals.com","logo":"@type":"ImageObject","url":"https:\/\/appuals.com\/wp-content\/uploads\/2022\/10\/apuals_new_logo_B-1.png","publishingPrinciples":"https:\/\/appuals.com\/about\/#go-to-editorial-guidelines","sameAs":["https:\/\/facebook.com\/appuals","https:\/\/twitter.com\/appuals","https:\/\/www.linkedin.com\/company\/appuals\/","https:\/\/www.youtube.com\/channel\/UCR--2QnA0vYBfqsmSI3pQ9g","https:\/\/www.crunchbase.com\/organization\/appuals"],"author":"@type":"Person","name":"Kevin Arrows","url":"https:\/\/appuals.com\/author\/admin\/","description":"Kevin Arrows is a highly experienced and knowledgeable technology specialist with over a decade of industry experience.
