I am using VB API for developing applications for my customers on Wildfire 4 until today and I had no problems with that during the last months....
Now I installed Wildfire 5 M010 and the VB API cannot be used for Wildfire 4 anymore, but WF5 is running well. I have installed WF3, WF4 and WF5 on one machine of course...
WF4 M100 and M120
The problem is that it's impossible to connect with the app to an already running Pro/E session. Again: WF5 is running well, WF4 not. So it's not a problem with my application code.
What I did to switch between WF4 and 5:
1. setting the environment var for pro_comm_msg_exe to the correct version (WF4 or 5)
2.Unregister the version I don't need with <wildfire_version>\bin\vb_api_unregister.bat.
3.Register the version I need with <wildfire_version>\bin\vb_api_register.bat.
In Visual Studio I checked the correct path to the COM reference in either WF4 or WF5. This settings are always correct (the path to pfclscom.exe), either to WF4 or WF5.
