I have installed Mathematica 13.3 on my Workstation by first uninstalling version 13.2.1 and got the error. Then I reinstall Windows 10 and 11 (clean install) on both my laptops and the error doesn't go away
Download MMA 13.3 from the site, and the problem will no longer exit. Try it.
No. I reinstalled Windows 10 and 11 (clean install) on two laptops and then installed Mathematica 13.3. The error remains for me.
After reinstalling the MMA 13.3, the problem is missing. Maybe the remains left from MMA 13.2 cause this.
It is working fine for me
