Hi Aamir,
You need to set your paradigm.ini file to have the complete short name for the service desk directory:
For Example:
[PARADIGM]
NX_ROOT=E:/PROGRA~2/CA/SERVIC~1
NX_LOCAL=E:/PROGRA~2/CA/SERVIC~1
NX_OS_TYPE=WINNT
[Product]
type=CA Service Desk Manager
version=14.1.0.111
NOTE: if you have ONLY the "Program Files (x86)" and not "Program Files" in the E drive, then the short name for "Program Files (x86)" might be "PROGRA~1"
Navigate to E:\ then run "dir /x" and it will show you the short name for all directories... see if its PROGRA~1 or PROGRA~2.
Then re-run pdm_configure.
I also updated jimka01 who owns your case so he has the same info.
Hope this helps, let us know.
Jon I.
