Startup Issues

If ProVAL will not start, the cause is most likely caused by a missing dependency or corrupted analysis templates.


Missing Dependency

ProVAL 4 requires the Microsoft Visual C++ UWP Desktop Runtime Package. If this is not installed, Windows will attempt to download it during the installation. If this is not possible, winget can be used to download and install the package. The id for the package is “Microsoft.VCLibs.Desktop.14”. 


Corrupted Analysis Templates

More commonly, startup issues are caused by corrupted analysis templates. Moving or deleting the Analysis Templates.pvat file will solve this issue. The location of the file can be in either of the following locations, although the first is more common. The file may not be present if no templates have been created.

  • %LOCALAPPDATA%\The Transtec Group\ProVAL 4.0
  • %APPDATA%\The Transtec Group\ProVAL 4.0

Alternatively, use the following locations by replacing [USERNAME] with your Windows username.

  • C:\Users\[USERNAME]\AppData\Local\The Transtec Group\ProVAL 4.0
  • C:\Users\[USERNAME]\AppData\Roaming\The Transtec Group\ProVAL 4.0

Error Log

ProVAL 4.0.71 and later will automatically send error reports to us, unless disabled in the Options.


ProVAL 4.0.68 and earlier do not send error reports to us but do save error reports in the log file, Event Log.xml. You can send this file to us. If ProVAL cannot be started, the file can be found in the same locations listed above. If ProVAL can be started, the log can be saved using the Save Logs item in the Help menu:
