Hello Community

I’m getting an error File format is not valid. when just click Help on Context Pane.

It seems to be my Windows installation specific, since i can’t open Help in any IFS EE app (we have 3 different environments). I already deleted all Apps 2.0 folders, nothing helped. 

Could you give me any tips what to check?

IFS10 EE Update 14

Client Version 10.5.8.0

Server Version 10.14.8.0

Error details:

Are you using Windows 11? I’ve just had a user get the same error in Apps9.

 

I had heard only recently that Micorsoft are removing .rtf functionallity from Windows 11 and WordPad but that maybe a coincidence.

Finally I was able to get rid of this error, by unchecking an option Beta: unicode UTF-8 for world wide language support in regional setting.
Full post on that resolution: https://answers.microsoft.com/en-us/windows/forum/all/richtextboxrtf-setter-throwing/31f1df32-f447-45f0-87f5-beebc1774092

To recreate the issue:

  • Enable Beta: unicode UTF-8 for world wide language support (To enable Start => Region & Language settings => Related settings -> Additional date, time & regional settings => Region -> Change date, time or number formats => select Administrative tab => Click on Change System Locale.. => Check  Beta: unicode UTF-8 for world wide language support checkbox

To fix it, just uncheck it.

Best regards,

Wiktor
