Hi Hartmut,
Though you have installed as administrator probably you didn't disable UAC when first installed version 5.91 If you keep UAC enabled you will get a lot of problems with amateur radio software in general if you install them in the C:\Program files folder because when UAC is enabled windows protects this folder and when running these programs system is really working with another folder located in (in case of Swisslog):
C:\USERS\YOURUSERNAME\APPDATA\LOCAL\VIRTUALSTORE\PROGRAM FILES\SWISSLOG (32 bits editions)
C:\USERS\YOURUSERNAME\APPDATA\LOCAL\VIRTUALSTORE\PROGRAM FILES (x86)\SWISSLOG (64 bits editions)
This is a bundle because user believes it's really working with the program folder in C:\Program Files\Swisslog. That's the reason I highly recommend to disable UAC and ALWAYS run installers in programs as administrator. In your case, though you have updated Swisslog as administrator, files in C:\Program files(x86)\Swisslog have been properly updated into 5.91a but when running Swisslog is really working with the copy located in C:\USERS\YOURUSERNAME\APPDATA\LOCAL\VIRTUALSTORE\PROGRAM FILES (x86)\SWISSLOG. That's the reason it won't find many files and creates a big bundle!
Please read this thread I posted explaining in detail all this about UAC and administrator rights:
