I am having an issue registering a 3rd party application (SolidWorks 2015 SP2) with Workgroup Manager 11.0 M020. I previously had WGM 11.0 M020 working correctly with SolidWorks 2015 SP2.
For testing purposes I installed SolidWorks 2017 and WGM 11.0 M030, registered SW 2017, connected to the test server and everything worked fine.
I then uninstalled WGM 11.0 M030 and attempted to re-install M020 via PTC installation assistant. WindChill File System and WGM install correctly, but SolidWorks sits at "pending prerequisite." WGM 11.0 M020 appears to have installed, but when I open it and click "register new application" nothing happens. TIA
I don't have anything but Creo with Windchill, but my guess is that you have a modified property file that has recorded the SW 2017 information in it and will not allow you to register a second version of SW.
See this other thread for a similar problem: https://community.ptc.com/t5/Windchill-Ideas/Supporting-multiple-instances-of-CATIA-in-WGM/idc-p/570...
I wasn't too sure how to delete the property file but I selected ONLY SolidWorks 2015 (I was doing 2015+2017) and it installed/worked. Thank you.
