Why this fits the old-PC constraint
The official guide names Windows 7 and says the package is both 32-bit and 64-bit compliant. That is materially different from editors that now require a 64-bit Windows 10 or Windows 11 installation.
Minimum requirements to verify
The published minimums are a 1 GHz processor, 1 GB RAM and 150 MB of available disk space. These are minimums, so large scanned documents and OCR may still need more memory and processing time.
- Windows 7, 32-bit or 64-bit
- 1 GHz processor or faster
- 1 GB RAM or more
- 150 MB free disk space or more
Buy only after a local test
Install the trial, open a representative PDF, test saving and—if required—run OCR. That confirms the real device works before the perpetual licence is attached to the account.
Limits to check before paying
- Modern security support for Windows 7 itself is outside the software vendor's control.
- OCR, activation, translation and updates require an internet connection.
- Test the current build with the machine's drivers before paying.
