Application Error 0xc0000022 [Solved]

Hello, ran into this problem after install and managed to solve it myself. Putting it out there if anyone else runs into it.


After installing Mumble and trying to run it for the first time I was getting an Application Error 0xc0000022. Googling turned up that this error is usually tied to a program trying to access a driver that has permission issues.


To figure out what drivers Mumbles installs I used a program called lessmsi to open up the .msi installer. Looking at the .dlls I saw that these two install to the system folder: msvcr100.dll and msvcp100.dll.

Doing a search I found those two files inside my C:\Windows\SysWOW64\ folder. I checked both on their permissions (right-click, Properties -> Security) it appeared that there were no permissions set up for me or Adminstrators at all which was most likely giving me the error.


To fix, I first gave myself ownership of those files. From a command prompt (running as Adminstrator), type:


takeown /f C:\Windows\SysWOW64\msvcp100.dll

takeown /f C:\Windows\SysWOW64\msvcr100.dll



Then I give Adminstrators ownership:


icacls C:\Windows\SysWOW64\msvcp100.dll /GRANT ADMINISTRATORS:F

icacls C:\Windows\SysWOW64\msvcr100.dll /GRANT ADMINISTRATORS:F



Using lessmsi I extract those two files from the installer to my desktop, make sure the permissions are good and then copy them over the older ones:


copy C:\Users\allan\Desktop\SourceDir\Win\System\msvcp100.dll C:\Windows\SysWOW64\msvcp100.dll

copy C:\Users\allan\Desktop\SourceDir\Win\System\msvcr100.dll C:\Windows\SysWOW64\msvcr100.dll


That's it! I'm up and running Mumble now with no issues (knock on wood)...
