- Type %temp% and press Enter to open your temp folder.
- Select everything and delete it (skip any files Windows says are in use).
- Empty the Recycle Bin, then try the install again.
3Confirm the temp path exists

Frequently asked questions
Is error 1622 caused by a bad TurboTax download?＋
Rarely. It's almost always about where the installer is trying to write its log file, not the file itself. Still, grabbing a fresh installer is a harmless thing to try.
Could a second Windows user account fix this?＋
Sometimes. If your main account has corrupted permissions, installing from a different administrator account can sidestep the problem.
