Hi Andrew,
This was helpful and solved the problem.
The new computer came with Microsoft Visual C++ 2015 Redistributable, and I had updated to the newest one, 2015-2019, thinking that might help. On your advice I installed 2012 and then the program worked. I haven’t had to install 2012 up till now so it must have been present on previous computers and not on this newer one.
Thanks for the help!
