Hi,
I already had tried the same but it didn't work.
The reason I figured out was different.
while installing the CMOD, the pdf folder was not installed in the package and hence the pdf reports will not open until the PDF folder is also installed with CMOD under the IBM32 folder(C:\Program Files (x86)\IBM\OnDemand32\PDF).
To find an alternative, i simply changed my view information tab in the application and made the type as - user defined and gave extension as pdf.
The reports are now opening properly.
thanks for the response!
