Recently installed and tried using the trial version of Unity3D (2.5). During installation, I installed the island demo and the web player. After starting up Unity, and having the assets load for the island, I received an error saying “Unity Alert - Fatal error! - PPTr(managers[m])->IsPersistant()”. I would click quit, and the program would then proceed to crash.
I uninstalled and reinstalled getting the same error. I then installed without the web player or island demo. It would then run, but I would get an error in the console saying “Too many instances of a gamemanager!” Then its says “Error in file:…..\Runtime\Misc\SaveAndLoadHelper.cpp at line: 764” in the bottom part of the console. There is usually more than 4 of these same errors in the console, but the number fluctuates all the way from none to 12.
I have been able to play around with the editor, and load the 2D Platforming Tutorial. When I go to play the game though, I get the first error “Unity Alert -Fatal error! - PPTr<Object(managers[m])->IsPersistant()” and the editor then crashes.
When I try to save my work (possible in trial version?) I get this error “Unity Alert - Moving File Failed - Moving D:/Data/MyDocuments/NewUnityProject/Temp/tempFile2 to D:/Data/MyDocuments/NewUnityProject/Assets/New Terrain 1.asset failed: Access is denied.” (Sorry for doing the whole folder location, just want to be accurate with this). I then have the options to Try Again, Cancel, or Force Quit. Force Quit is the only one that works, and it crashes the program rather than just quitting the application.
There are others at my school who are having the same problems, and some who have no problem at all with any of it. All of our video drivers are up-to-date, and we usually don’t have any errors with other applications (these are the issued computers for the college).
Any info would be great, sorry for the novel. Cheers
Welcome to Unity and sorry about the weird behavior here. The Island demo is installed into a shared user directory, do you have full read/write permissions to that folder? If not then perhaps that’s a part of the problem. I’m not sure how/why but it came to mind as a question to ask.
Yes, I have full administration over all directories of the computer. I haven’t tested it out in a more open area (say the desktop) but I will in a few moments here.
Yeah, I thought it was interesting too that it said I didn’t have access.
[Update]
Yeah, just moved the project folder and created a new project folder on the desktop and tried saving. Still getting the error with Access Denied. Still gamemanager error also.
Can you make a video of the install process and/or launching Unity and attempting to run?
Use http://www.jingproject.com/. It’s simple to create and upload your video. Just paste your link here once it’s uploaded.
If you’re not able to make a video, then can you provide a little more details about your setup (OS version, Disk free space, graphics card, network drives?)?
OS: Windows XP SP3
Graphics Card: Nvidia Quadro NVS 120M - 512 MB - Forceware version 83.13
RAM: 3.25 gb
CPU: Intel Core Duo T2500 2.00GHz
Free space on harddrive: C = 6 gigs, D = 16. I have put unity on both C and D to test.
Regarding the first issue: does this happen only when you create terrains? What happens if you create a new Project, Save out a Scene, and exit?
Regarding the second issue: How come you didn’t get this error the first time you launched? Does this happen only after restarting Unity when the first error occurs? If the error messages don’t crash Unity, then the error may be benign.
Aras, another developer here, brought up something that I seem to have forgotten. Are you running anti-virus software? If so, then try disabling it to see if that fixes the problem. Anti-virus software can delay the writing of a file or prevent writing of a file.
I created a new project, saved the scene, and exited without a problem (not creating terrain). I had the project load up the Standard Assets Package, and now I can save without any errors. Could it just have been the terrain? I do get another error now saying the following:
Failed to set paths for drag and drop

As for the gamemanager error, it occurs randomly from what I’ve found. Sometimes it has it, sometimes it doesn’t, and in different numbers. I’ll start it up, and get around 4. Next time I could get none, or 10 of the same error.
I turned off my anti-virus (AVG 8.5 Free version) and it started up without any gamemanager errors for the first to startups. Then I recieved the gamemanager error again.
Was this before or after you disabled anti-virus? If you create other assets (e.g. materials) in your project folder do you get any similar errors?
It looks like you were trying to drag a file into the project window? I take it this operation failed?
If this error is not causing Unity to crash or functionality to fail, then it is most likely benign and possibly a side-effect of some of the other file-writing issues you’re experiencing.
Unfortunately, I’ve seen that even with disabling an anti-virus through the taskbar that some AVs still run services in the background. I’ve seen this personally with PC Tools AV and 3dsMax, which was causing 3dsMax to fail launching. If you’re really bold you can try uninstalling the application temporarily to see if that frees up Unity. If that fixes the case, then you could reinstall AVG or another free anti-virus (Comodo is what I use) and make sure the AV excludes Unity and Unity project folders.
If you’re worried about uninstalling your AV, then at the very least you might want to check what other application is accessing your project files with FileMon:
