Question: When startup AutoCount Server, an error prompted “System.Windows.Markup.XamlParseException: Set property ‘DevExpress.Xpf.Core. ThemeManager.ThemeName’threw an exception.”
Possible Reason :
.Net Framework was not installed properly or Windows unable to detect the .Net Framework.
Solution :
Reinstall .Net Framework 4.8. Then restart computer.
Or uncheck .NET Framework 3.5 and .NET Framework 4.8 from Window Features, and restart computer.
After restart check both .NET Framework and click on OK.
