2) Test if really all *.auc file have been deleted using MS-DOS command: del *.auc /s for the AX clients in folder (default): C:\Users\MyUsername\AppData\Local (Note: “MyUsername” needs to be replaced with your corresponding user name)

3) Check if Citrix terminal server or roaming profile settings might have an impact here?

4) Check if .NET Framework fixes (manual or via Windows update) might have an impact here by applying the latest fixes ?
