Hey everyone. I cannot get Unity to start on Windows 7. I have two versions installed - 2020.3.37f1 and 2021.3.11f1. I get this error in both:
Failed to start the Unity Package Manager local server process. Make sure the process [C:/Games/Unity 2020.3.37f1/Editor/Data/Resources/PackageManager/Server/UnityPackageManager.exe] is not blocked by Windows Defender or any other anti-virus configuration.
Click on Retry to relaunch Unity and reopen your project.
Click on Diagnose to launch the Unity Package Manager Diagnostics tool.
Here is the diagnostic report:

I tried disabling my firewall before launching Unity, I don’t see how that could be the problem. Is there a Windows service that needs to be running? Or may a Windows update that is required? I don’t know what to try that I haven’t already tried. Any help would be great. Thanks for reading.
That’s what I think too, but as I said, I disabled my firewall (I even uninstalled it and tried when it wasn’t installed), and I don’t have any anti-virus apps. That’s why I’m asking about services or updates, I can’t think of anything else.
As far as Win7 not being supported by MS anymore, I don’t see the relevance. It says this on the download page:
Unity Hub system requirements
OS:
Windows 7 SP1+, 8, 10, 64-bit versions only; Mac OS X 10.12+; Ubuntu 16.04, 18.04, and CentOS 7.
Based on that I would think it’s reasonable to think that the editor should still work in Win7.
same problem with no solution.
“If you convert that exit code to hexadecimal, it is C0000139, which is “Entry point not found””
if you directly launch “unitypackagemanager.exe” you might have anything about “entry point not found” + “avdapi32.dll” which may be related.
I stopped the search here.
can add **-**noUpm to shortcut to launch unity without unity project manager but not a real solution.
Thanks for that, I can actually see the editor on my screen for the first time. Dumb question maybe, but I have zero experience working in Unity: Does not running the package manager make Unity unusable? Are you able to work around it? Right now I’m mainly interested in making custom objects for Parkitect.
Sorry I can’t answer your questions since I have no idea about the use of unity package manager. I haven’t really used Unity since years, just tried to open a discord project recently in vain with the same issue as you and didn’t go any further.
I don’t know Parkitect but If you just want to do custom objects maybe dealing with packagemanager is not necessary… l:
Others ideas without noupm :
I have read that there were “recent” versions of Unity without the projectmanager bug : 2021.1.22 (last post). Maybe you can try the copy-paste thing that he wrote as well if you want to try it on 2022… (edit : he says as well that KB3080149 doesn’t help contrary to the second post x_x)
If you don’t care about taking risks with window updates you can try this at your own risk (KB3080149 - on the same topic - first / second post)
