Strange problem. I have been using unity for several months without issue. This morning I tried to launch unity and I get the error “Error #-61 while verifying your authorization. Permission for this file doesn’t allow writing.”
I tried removing and reinstalling Unity with the same results. Are there system files I need to change somewhere? i don’t think I have made any changes to my machine lately that could cause this.
Does anyone know how I can fix this?
A forum search (my Google version) shows that this has come up before but Sam didn’t seem aware of what exactly it meant. So my only suggestion is to:
Quit out of Unity
Find and delete the following file:
HD/Library/Application Support/PACE Anti-Piracy/License Files/Unity_v2.x.ilf
Empty the Trash
Relaunch Unity and re-activate using your serial number (this will not burn/waste one of your allowed installs as it’s being done on a “known” machine).
See if that helps and if not then we’ll give it another go.
Sweet that worked. Do we know what causes this? I partitioned my hard drive to install XP via bootcamp. Could that have caused this?
My guess is that whatever you did changed the permissions on the *.ilf file preventing Unity from reading it and knowing if you were properly licensed or not. By deleting it, then following those steps you simply created a new version of that file, without the whacked permissions.
