Can't install Launcher (Error Code 2908)

Development Getting Started & Setup

1

I have tried different installers from the site, however every time I try to install the launcher I get the warning,

“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2908.”

After I press OK it brings up a new warning saying

“Could not create key: UKNOWN\Components[lots of letters and numbers]. Verify that you have sufficient access to that key.”

Any help would be appreciated.

Hey Conmanlang,

I have tried to reproduce the issue, and was unable to get the same error as you. Are you able to download the launcher from UnrealEngine.com? If so, does the error occur after you’ve began the installation process, or before anything has actually started to install?

Also, are you on Windows or Mac?

Please provide as much information as possible, so I can further assist you.
Thanks, looking forward to hearing from you!

I can download the launcher from the website and run it. As far as I can tell it all takes place in the setup without anything actually installing. I select the install location and get the first message when the wizard is “Updating component registration”. After I click OK the status changes to “Copying new files” and then I get the second error message. It then starts to roll back and closes the setup wizard.

I am using 64-bit Windows 7 Home Premium Service Pack 1.

Hey Conmanlang,

Thank you very much for providing us with the debugging . After reviewing the , it seems that the error links back to VC Redist 2011, specifically msvcr110.dll.

Could you please check and see if you have a version of Visual C++ Redistributable 2011 already installed that might not be working correctly? Or perhaps find a Microsoft installer to run separately first?

Once you’ve done that, try to install the Launcher again. If that does not work, please reply back to this thread and we’ll assist you further.

Thanks!

I have tried uninstalling and reinstalling the redistributable but it still gave me the same errors when I tried to run the UE setup wizard.

Find this file: C:\Windows\SysWOW64\msvcr110.dll and rename it to msvcr110.dll_BACKUP. Then run the installer again. If that does not fix the issue rename it back. The installer seem to imply that this file may be corrupted and/or perhaps something is odd with the permissions on that file.

That seems to have done the trick. Thank you very much.
