Help installing WPILib

Hi, I was trying to install WPILib for Windows 10 64 bit, but I encountered an error. I think the error occurs because there is no “.gradle” folder, but I have no idea how to get it.
Here is the error:

System.UnauthorizedAccessException: Access to the path ‘C:\Users\User\ .gradle\wrapper\dists\gradle-7.3.3-bin\6a41zxkdtcxs8rphpq6y0069z’ is denied.

The “access denied” suggests to me that running as administrator might fix it–have you tried that?

#3

Yes, I tried running as administrator.

I assume you already tried a reboot. Sometimes something grabs access. Also, if you have any 3rd party antiviruses (anything besides Windows Defender), go ahead and disable those.

What is the user name of the account you are installing on?

#6

Don’t know if you were installing for ‘current user’ or ‘all users’ . Unless there is a need for all users try just current user.

I got it working, thanks.
I used task manager to end all unnecessary tasks, including McAfee, and figured out how to install it as an administrator.

Unrelated tangent: For future reference. Nearly all Antiviruses use the same databases and technologies.

In my not-professional opinion, their all junk and computer literacy saves vulnerable people more than AV.

Indeed, and these days Defender is surprisingly robust on its own! Though I do still recommend MalwareBytes to those who still want an additional AV. While you of course can still run into these sorts of issues, I have found false positive blocks/errors to happen less commonly, especially compared to Norton and McAfee which are practically malware themselves in my opinion.

  • I am a cyber security professional, though Desktop/Workstation AV is certainly not my area of expertise.
