Well, and the need for a 32-bit windows of course.
Yes, up until Windows 10 there was a 32 bit version of Windows. But not anymore for Windows 11.
So when those customers want to upgrade Windows or PC, they'll need to go to vDos or something.
And in BP on 32 bit Windows I had PDF creation, E-Mail, copy/paste to Windows and Windows-printers support build in, which they will lose in vDos. Only option then would be a VM for them.
But they can always upgrade to the Windows version of the program (which for some reason, read a few €, they never did)
