Hello,
We are in the process of upgrading from Crystal Reports 2016 to Crystal Reports 2020, and have been running into issues using our custom function library. Now that 2020 is 64-bit, our functions don't show up in the Crystal Reports Designer, which will cause us issues. When compiling the library in 64-bit, it restores the functions in the Designer, but it then causes the Viewer in our 32-bit system to not load the reports. We have tried updating the support pack for visual studios as well, and that did not work either. Updating our entire application to 64-bit is not an option, is there some way to restore the Designer's functionality while not disrupting the Viewer?
