You won't need to reinstall SOLIDWORKS, just modify the SOLIDWORKS PDM program in the Windows Control Panel. During setup see p.92 of the 2017 PDM installation guide. This will show you how to activate the SOLIDWORKS PDM add-in. The part you will need to make sure to follow is the section below called "Select Add-ins".
The Add-in would also need to be manually updated to 2017. The Add-in are not upgraded when the Vault and systems are upgraded.
I also had similar problem,
When I moved from win7 to win10 the addin not loaded.
finally I founded that in order the add-in will be loaded automatically, I had to create new file:
the filename is "protk.dat"
The location for this file must be in the text folder, under the installed folder of your proe.
this file should contain the following text (without the quots):
exec_file C:\Program Files\SOLIDWORKS PDM\FileFormats\PTCAddin_x64.exe
text_dir C:\Program Files\SOLIDWORKS PDM\FileFormats
*- verify that you have these two path (C:\Program Files\SOLIDWORKS PDM\FileFormats, which is the installed folder of your Solidworks PDM Professional. and check that you have the file: "PTCAddin_x64.exe" in this folder). in case your installed folder of Solidworks PDM professional is different, edit the path above.
**-in case you already have this file (protk.dat), just add the text above and save the file.
I have different problem now:
I can can manage Proe files from Proe only. any edit of properties (PDM Data card) from explorer window lead to error.
