Setup error after new download

Getting setup error repeatedly. I download audacity for Windows (current version: 3.0.3), launch setup and get immediate error: “Setup was unable to create the directory [in my user path]\Local\Temp\is-0B4T0.tmp” I’ve deleted the setup executable, got new download of file, and restarted my PC - all several times - still same error. Please advise. Thank you!

There was a time in which I deleted a temporary folder. When it had to be created again, it was created with a permissions setting that didn’t let any installer to put files in, that made impossible to install almost anything.
Go to that “Temp” folder, and edit its permissions to ensure that any generic user can modify its content. That should work.
