After having upgraded to the library’s latest update (“Update All”), I have the following error message appearing on next startup. I can go beyond the message but the library appears as if it wasn’t updated.
In this message there is a line for each package which was supposed to be updated.
Hi, sorry to resurrect an old thread but I had, and fixed, this issue too. Newly installed modules extracted no problem, but updates could not be extracted. Deleting the existing plugin files from Documents\Rack2\Plugins\ allowed them to install fine, except the Fundamental modules. (Maybe because there’s another copy of them elsewhere?)
Anyway, the problem was caused by Avast Antivirus File Shield, I disabled that temporarily and all the modules extracted as expected.
… and make lots of other things fail too. I’ll say it again: You only need the Defender antivirus program built into Windows and nothing else, it’s very good. Third party antivirus ranges from simply a nuisance, to incompetent, to dangerous to criminal. Just don’t use them.
