XamlParseException at startup: application not showing

[BrainCrumbz]

Environment

1. OS version: Windows 10 64 bits
2. Total-Uninstaller EXE version: 1.0.0.0

   Steps

3. Download exe from github, Download zero install exe
4. Unlock TotalUninstaller.exe from file properties, General tab
5. Run TotalUninstaller.exe as administrator from context menu

   Expected behaviour

   • Application should start regularly and show up its window

     Actual behaviour

   • It seems like application starts, as the wait spinning cursors shows up briefly, for maybe a second. But then no window shows up, and no TotalUninstaller.exe process is listed in task manager.
   • Checked logs in %APPDATA%/TotalUninstaller, and all the tries I did report the same. Here below the full log. Short message translation follows at the end.

I am having the same issue. I use Windows 8.1

Thanks for the report both. Apologies for the delay(!). I've taken a look. It looks like it's having trouble parsing the product version of one of your installations. I've released a new version (v1.0.1) which should handle this case, and just report '0.0.0.0' if it's unable to parse the version.

If you guys could give it a test and confirm the app now loads that would be great. It should also log the offending application in the form 'Count not determine product version for 'XXX'. If you could let me know the specific install causing trouble I can look into exactly why the version parsing fails.

Thanks
