I was able to use Unity in the past (about 2 years ago), but not anymore. I can’t even open past projects.
Unity hub is unable to install any editor of any version. I’ve download different version, each time it got stuck on “Validating …”.
I’ve tried to install unity 6. I created a brand new project but even a new project has compilation error and cannot work. I’ve tried deleting “library” folder, shut down my antivirus, shut down my VPN. deleted the unity cache. Reinstalled several times. Restarted my computer. I asked stackoverflow, google, chat gpt. No solutions has worked.
Any idea?
How to reproduce problem:
- Install unity 6 manually without unity hub; create new empty 3D core project.
- Try to install any editor using unity hub. Get stuck on “validating…”
Hypothesis: There might be a problem with my CMD, which I also don’t know how to fix. It opens and close immediately.
EDIT:
My hypothesis was correct and I found a fix by pure chance.
see:
- I’ve changed an env variable,
- and deleted a registry (autorun) as instructed in the above video.
One of these 2 or both things fixed my CMD issue AND now my unity hub is installing correctly. AND my editor is not throwing compilation errors anymore.
I’ve seen some people with similar issues. Please share. The fix is extremely easy to implement (assuming its the same cause), but hard to find.
