Thank you for your help! Repairing the .NET installation solved my problems Regards Hans

Addition: I can start the apps with Run as Administrator. But why should that be required, my computer account doesn't have any restrictions and doesn't cause any problems with other apps. ???

Thanks, So to answer a few question raised: Windows version: 23H2 I have tried installing using both MSIX and MSI/EXE installers. (all installations runs smooth wit the same end result) I get the following errors in the event viewer, apparently related to .NET (both with Designer version 2.4.2 and Photo 2.5.7 Application Error Faulting application name: Designer.exe, version: 2.4.2.2371, time stamp: 0x660d2be1 Faulting module name: KERNELBASE.dll, version: 10.0.22621.4751, time stamp: 0x2db246bf Exception code: 0xe0434352 Fault offset: 0x000000000005fb4c Faulting process id: 0x0x726C Faulting application start time: 0x0x1DB6EFE3D5F858E Faulting application path: C:\Program Files\WindowsApps\SerifEuropeLtd.AffinityDesigner2_2.4.2.2371_x64__3cqzy0nppv2rt\App\Designer.exe Faulting module path: C:\windows\System32\KERNELBASE.dll Report Id: 8e988b53-1329-4c8c-9554-3bd7267399a2 Faulting package full name: SerifEuropeLtd.AffinityDesigner2_2.4.2.2371_x64__3cqzy0nppv2rt Faulting package-relative application ID: SerifEuropeLtd.AffinityDesigner2 .NET Runtime Application: Designer.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception.

After upgrade to latest official version of today (Jan 24, 2025) none of the apps will start. I can only see a few seconds of activity in the task manager. I Googled and found that this was a known problem and a solution was to join the Beta program and install the latest Beta version. I have done so today, but still the same result. Does anybody have a suggestion to what to do? Thanks
