Several people, including myself, report an error. After installation of TB, MS Visual C++ will be installed. This has been standard for some time.

Now at the end of that installation, you may get an error:

"Error in executing ....\TheocBase\vcredist_x64.exe /install/passive/norestart: Program ended with an error exit code"

Just before that message you get an explanation in your OS language that says 'Problem in executing post installation step. Installation may not be completed properly', or something of that kind. The thing is that in some languages the message seems to imply installation failed, and in others that it just might have failed (which means it might have succeeded as well).

Suggestion: OK the error, and see if you can start and use TB all right. Some have reported that they encountered no problems at all after ignoring this message.

If TB does not work (except for the splash screen only issue, see release notes for that one) you may have to find additional info on this forum (which is there).

Hi to everybody. 

I posting here because I experienced some similar problem. 

Opening the app takes very long time and when I click on button to change the week or to open right-side menu to edit/choose the speaker for public talk, the app is crashing. 

I choose debbug option (open in Visual Code) and I saw reference to vrfcore.pbd and vrfcore.dll files. 

I googled and I found this solution that worked for me:


rfcore.dll is used by Application Verifier and it creates registry entry also in some cases. Make sure you are not deleting or changing anything else while doing the following step:- Goto Registry editor-> win+R->regedit->HKEY_LOCAL_MACHINE->SOFTWARE->Microsoft->Windows NT->CurrentVersion-> Image File Execution Options -> (Your application name.exe). ->Right Click and export the registry settings for backup. ->Delete the registry entry for your application and try to run.

Hope it works.
