When I read that the new version of Pale Moon for Atom/XP was available I did the update from 25.8.1 to 26, but when I have tried to start the program I've seen this message:
Unsupported Operating System
So I did go back to the previous version.
I have looked at their forum and I read that PM wasn't compatible with POSReady 2009, so I think that now the program check the registry before starting.
How can I run now the new version of PM?
