> I think you will not get an error but a warning

Xiaofan, I installed 8.30 (Programs\Microchip830) as well as the
already-installed 7.50 (Programs\Microchip). 8.30 works OK
but 7.50 won't get past the splash screen with the message

"Unable to create the display plug-in (long number)"

Disappointing
