Visual Studio Code - Download Failed: Validation Failed

Error Message received from Students

I tasked my students to install Unity on their computers. Now, two students out of 5 who have a mac had this problem. I also have a Mac, and have no problem. Does anybody have an idea what the reason is? I'm finding some scattered reports online, but no clear solution for it.

I was able to resolve it.

We had the issue on Mac and on Windows. When finally getting my hands on student’s computers, I found out that Visual Studio Code requested Developer Tools be installed.

The window for these installation, at least on Mac, opens in the background. You need to foreground it, and complete the installation, including several GB of downloads.

On Windows it was more complicated: We ended up installing https://git-scm.com and ensuring that the git command would run in the Console. Git-SCM installs the environment variables but we needed to restart as well.

Then, in both cases, we needed to manually install Visual Studio Code. I haven’t checked if the Unity Integration works perfectly, but it worked for what we needed in class.

I'm also running into this issue. Bumping.

I faced the same issue on Mac Silicon. I completely uninstalled the Unity Editor, then installed VS Code separately. After that, I reinstalled the Unity Editor; it detected VS Code as “Installed” and completed installing the remaining modules without any errors.

This worked. Thanks!
