Perforce in Unity 4.5 missing all the settings, says "Executable error"

We were using Perforce in Unity, but when we upgraded to Unity 4.5, two of our team members had their Perforce support broken. When we go into the Version Control settings, most of the settings are missing and it says "Version Control executable error".

Any ideas? This is severely hampering Unity's usefulness to those two team members.

 

Unfortunately, the most recent change to p4plugin.log was a successful login from April, so that doesn't help much. Is it possible that the minimum version of Perforce supported changed in 4.5, and these two people don't happen to have that version?

 

They are on OSX. Not sure about PerforcePlugin, dunno how to check for running tasks on Mac, but it's really strange that it happened on two separate computers the moment they upgraded to 4.5, and was working perfectly before that. In fact, the second guy didn't want to update because of what happened to the first one, and then it happened to him. Just to note, we have a number of other computers that did successfully update to 4.5 and keep Perforce working.

 

If some computers are working and some are not, then it sounds to me some setting are different on the broken machines,so your saying they all using same version of osx go check all the machines because apple do . Point releases to the osx..click the apple icon on pc and goto about.:

 

Sadly this happened to me today but it seems that due to VPN connectivity issues and the client locking up on me, after having to forcefully shutdown Unity somehow the perforce plugin is not running any more, perforce works flawlessly but the unity plugin is not there, I've tried restarting everything including my PC, re-installing the same version of Unity over ( Release 4.5.2f1 for WIN- not a clean install) - nothing I did enabled / fixed the perforce plugin, this is the errors unity is throwing at me (I can never connect to perforce because of this):

Cannot load Perforce overlays when plugin is not running.

Version Control executable error.

Any and all help is highly appreciated.

PS this had been working correctly since July on an every day basis until today (12/01/14)

 

Bump, same problem as @LedMirage

 

@KiritoDeathgun - The exact same thing happened to me. I managed to fix it by reselecting Project Settings > Editor > Version Control > Mode > Perforce a couple of times. It refreshed and brought all my settings back and I managed to Reconnect my Unity to Perforce.

Good luck.
