This is some shady software and company! I would advice staying away from this crap. Reasons:
1. MSTech Office Home requires .Net Framework 4.8 installed or it will fail.
2. The Installer is not digitally signed.
3. After Installation, does not appear under Programs in Start Menu (Windows 10).
4. Requires ADMIN access to run! (WHY does a WORD processor and PDF reader need this??).
5. MSTech Office website has their domain info REDACTED and Registrar is in Al Batinah, Oman (Very shady for a legit business).
Be very careful if you want to willingly use this software, as oppose to legit free alts like LibreOffice, OpenOffice or Softmaker FreeOffice. This is usually how PCs are hacked and used DDoS bots.
