Hello,
I have both PB 12.5 and PB2017 installed on the same PC. One of my applications uses a custom ocx. A few weeks back I migrated it from 12.5 to 2017. Everything worked as it should - ocx and all. Then I had to unregister the ocx to do some testing and a day later I registered it again. Now PB2017 refuses to recognize that ocx - "Error calling external function..." error. But the 12.5 version of the same app on the same PC works great.
Any ideas how to fix it?
Thank You.
