I led a Paratext beginners workshop a couple of weeks ago. Some of the participants weren’t in official translation projects yet, so people brought all sorts of different ages of computers… whatever they could get their hands on. On the Paratext download page it says that Paratext 9.1 requires Windows 8 or greater, and a 64-bit OS. There were several computers where we couldn’t install Paratext 9.1, and one of them was in fact Windows 7, but I think all of the others where the install failed were old versions of Windows 10 (like from 2015 or 2016). I assumed that they must be 32-bit machines, but one of them I specifically checked and it said that it was a 64-bit machine. (I don’t remember the details, but the installs all failed in the same way, so it wasn’t just some random installation failure, but a failure to have the right kind of OS for installation.)
Unfortunately, I don’t have access to the computers anymore. I jotted down a couple of notes of Windows 10 versions from a couple of the machines, but I’m not even sure how to decipher my scribbles now: for one “1511 10.0 10240 @2015” and for the other “10.586.0 @2016”.
So the question is, is there a minimum version of Windows 10 required, or is there some dot net library or something required that old Windows 10 versions don’t have?
Fortunately, I believe we were able to install Paratext 9.0 on all of those machines, but that also caused some confusion for these beginners, when things on their screen weren’t the same as on the presenter’s screen.
