I installed PA to a cloud drive, pCloud. And a few apps are giving me a similar error message. Most notably the PA platform when I try and close it. A box pops up and says:
Unable to write to P:\Portable Apps\PortableApps\PortableApps.com\Data\PortableAppsMenu.ini
This box cascades on my screen, and I am only able to get past it by invoking task manager and ending the PA process.
Another App that gives me a similar message is FileZilla when I try and close it.
I'm on Windows 10 using pCloud.
