Looks really complicated to get Crystal Reports installed.
However, I installed v6.3.3 on an new Win10 machine, then rebooted, then installed v9.4.3 over the top of it.
It automatically removed the 6.3.3, leaving Crystal Reports intact, and installation proceeded smoothly.
I got one more Installer Interrupted error at the very end -- but all that was was it was looking for the main server. Pointed to the AC.xml and all is well.
