The version of Passolo installed on my computer was 22.0.207.0 when I was prompted to update it to ver. 22.0.239.0, so that was what I did. As a result, the psl.exe file got removed from the program folder. I uninstalled Passolo ver. 22.0.239.0 and tried to install version 22.0.207.0 to the same location, but I got an error saying that the files could not be installed to that folder possibly due to a permissions related problem. Personally, I do not think the error message was correct because I ran Passolo2022.exe as an administrator. I started installing version 22.0.207.0 to a new location, and I got a different error saying that the shortcut to the psl.exe file could not be created. Since the file did get installed, I created the shortcut myself. The program seems to be working fine, but I do not risk to install the 22.0.239.0 update any more.

I wonder if anyone has encountered the same or similar problem with the 22.0.239.0 update, and if there is a way to avoid it.
