I have entries in "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\App Paths\pb..." for my PB IDE's (pb170.exe and pb125.exe). I installed R2 on the 6th and it seemed to work fine but I cannot recall if I ran my application through the IDE then. The next morning my PC went through a Win 10 Patch. After coming back I was unable to run my app through the either IDE (PB 2017 and 12.5) because it could not find a DLL that we use. I tracked it down to that the App Path is not being included when PB starts. If I Right-click and Run as Admin then the App Path will get used and my application will run. This is only an issue with PB - other applications that use an App Path work just fine.
So, can someone validate that their App Path works? From what I can tell R2 or Patch has messed me up but I do not know which one.
