I'm not sure why you're suggesting what you did, but thank you for your promise.

As I've said, I've already uninstalled and reinstalled all programs.  I've done it without the 2016 and with the 2016.  I have a brand new HP laptop and it's way past the system requirements.

There seems to be some kind of problem that either QB program has exporting the file.  When I uninstalled all the programs and then reinstalled only QB 2019, it still had the problem, even without any version of Excel on the PC.

Isn't there a high-level QB tech who can address this programmatic issue?
