Robin, we’ve had PDF Architect 4 installed on Windows 7 in our office for quite a while. We just recently upgraded to Windows 10 and PDF Architect seemd to work just fine…UNTIL…we received a notice to upgrade. It keeps failing the upgrade so I uninstalled the program completely from one of our Windows 10 machines and tried to reinstall. We then got the very same issue as Ayoffa stated in his post.
I attempted your recommended fix but the C:\Program Files\ location was already in the destination installation section. The problem still occurred and when I checked the error message, it gave the exact same thing…trying to install to P:\ drive.
Since this is happening on all of our Windows 10 computers, it appears there is a bug in the installation file and most likely in the upgrade file as well. Let me know of any other workaround.
are you using Windows 10 home or pro?
Which version of the installer are you using?
I wasn’t able to reproduce this error on a Win 10 Pro VM.
If you like you could try using the MSI instead until we have been able to reproduce/fix this issue.
