QB Issue Resolution:
It sounds like the primary interop assembly (The connection between QuickBooks and Office) did not install. It’s rare, but most often it happens if QuickBooks is installed before MSOffice. Look for C:Program Files (x86)IntuitStatement Writer 2017vstor.exe and run it on the affected computer.
* If you are asked to repair or remove the primary interop assembly, remove it, then run the vstor.exe program again to reinstall it.
If you don’t have the vstor file, I recommend a clean uninstall of QuickBooks and then a reinstall.
I hope this helps. There is a detailed article that you can access as well, but try the two options I suggested first. I have had great success with them in the past.
