Could you please check the path using run. Looks like there is break in the path which is actually causing the issue. Request you to copy the path in notepad and check if you are able access using start-->run. If yes, then would request you to copy the same path and include in PB path. Looks like you want to access PB workbook .piw (file extension)
I did try to access the path and i am able to see the file in the shared path.
How do it update the PB path.
The problem is when i try to open processbook it is trying to access this path.How and where can i check this?
