Fantasy Grounds not upgrading

[Fazakerley]

My client tells me that there's an update, but when I try to update it, I get an error reading "HandleFile Unable to save file (FantasyGrounds.exe)

This also means that my players who have the basic account can't play as they get a message saying that I'm playing with an illegal copy of the software.

Any ideas?

It may be a permissions issue although it shouldn't be if it's the installation files that's the problem. Is your FG client in the default location?
