When i try to PDFView Command in Winshell I'm getting the below error. I'm using Winshell 18.104.22.168

Long story short: it seems that AcrobatReader is sometimes very unhappy with relative paths to a file so you have to spoonfeed him the absolute path. This can be done by using the following script instead of the plain Reader executable:
What disturbs me a bit is that the post that solves the problem is from 2008 but the problem occurred after a very recent update.
I figured out the problem. If the Acrobat Reader is not open and if I try to give PDFView command it prompts the above error.
However When I kept open the Acrobat Reader and give the PDFView command it works.
