I have discovered that I need to turn off IDrive completely when installing or upgrading random software otherwise it just fails. Apparently it is due to unauthorized write access.
What I don't understand is why would IDrive mess with some part (folders) of my system that are in no way related to the scheduled backups I use it for?
I'm really getting tired of it. I like automation but if it is for having to add random manual operations on top it really makes no sense.
Also the issue is relatively well documented on google, I'm surprised I didn't find anything on this forum.
