I recently upgraded my PLC Programming PCs running Win7 Pro from Automation Direct (automationdirect.com) Productivity Suite v220.127.116.11 to v18.104.22.168. When I did so, my file association for .adpro files quit working forcing me to open the Productivity Suite software first and selecting the project file to open instead of just double-clicking the .adpro file in Windows Explorer.
I emailed Tech Support and they had no fix. They told me to do a Google search…
After some investigation, I found that the v22.214.171.124 installation was failing to update the file association links in the registry. They were all still pointed to v126.96.36.199
"C:\Program Files (x86)\AutomationDirect\Productivity Suite 188.8.131.52\Productivity Suite.exe" "%1"
You can either use regedit.exe and search for this string replacing the version number in all instances or simply download this excellent file association tool from Github: http://ystr.github.io/types/
After installing Types, you can right-click an .adpro file in Explorer, select ‘Edit file type’, and change the ‘open’ Action to point to the correct version.
