We are a student engineering group that has used PDM workgroup for several years and for the most part it has worked very well. The PDM is on a server that we maintain and during the update to SW 2017 we ran into trouble. In the solidworks installer we selected the upgrade option as we have PDM 2016 SP2.0 installed already. It then gave Error_1. The solidworks install on individual PC's worked perfectly so we know that the serial number we have works, which makes error_1 confusing. We pressed the back button and re entered the serial number and then pressed next with no problems. On the summary tab it said we could only install not download the file and would need a DVD(which we don't have) to finish the install. When we press install it gave error_2 and would not let us proceed any further.
Any help resolving this would be very much appreciated! Let me know if you need more detail or have any questions
