UPDATE: ISSUE HAS BEEN RESOLVED. PLEASE CLOSE THE QUESTION.
I'm having issues getting the downloadable version (only version available now) to install on my PC. I'm using Windows 10. I have 1.6 GB of space (TT required 1 GB) . I have: cleared my cache; history and downloads; turned of Windows Defender firewalls; got error code 2755 and ran the Windows Installer repair troubleshooter (report said it could not find issue); restarted computer. I just ordered the CD version for $10 extra dollars to try and install that way as I've never purchased a downloadable version. Any other thoughts would be greatly appreciated.
