When I try and simulate my circuit, which is just a buffer made up of two inverters back to back, I get the error messages shown below:
WARNING -- Library file C:\Cadence\SPB_16.3\tools\PSpice\Library\infineon.lib has changed since index file nom.ind was created.
WARNING -- The timestamp changed from Thu Jun 21 17:50:36 2007 to Mon Jan 04 11:42:56 2010.
Making new index file nom.ind for library file nom.lib
ERROR -- Unable to open index file C:\Cadence\SPB_16.3\tools\PSpice\Library\nom.ind. Refer to 'How PSpice uses model libraries' section of pspug.
ERROR -- Unable to make index for library file C:\Cadence\SPB_16.3\tools\PSpice\Library\nom.lib
ERROR -- Subcircuit INV10_H is undefined
I have added both the NOM.LIB and the other LIB file that contains the INV10_H design as global libraries in simulation settings options window but the errors are still coming up.I thought the problem had something to do with the C:\ drive being READ ONLY so I tried moving both files to another drive and added the LIB files from there but errors still show up IN THE EXACT SAME WAY even though I added the new path in the list of library paths, which I think may mean the ORCAD PSPICE program is refusing to change the path from C:\ to H:\ for some reason.
Please Help.This is my first design :(
Yes,you need to provide write permission on C drive, more specifically for "C:\Cadence\SPB_16.3\tools\PSpice\Library" folder. If you can not do this, move the complete library folder anoter location where you have write permission, say H: drive.
Open the PSpice.ini file from C:\Cadence\SPB_16.3\tools\PSpice\PSpice.ini location
Edit the LIBPATH sestion and replace existing lipath with new path.
Adding new path would not help, as PSpice would still try to create the index file for C:\Cadence\SPB_16.3\tools\PSpice\Library\nom.lib. Looks like this is case at your end.

In reply to KillaKem:
Copy the PSpice.INI file to H:\ or other location, along with Library files. Edit the PSpice.INI as described above.
Then you need to edit the registry entries, I am not sure if you have permission to modify those. in case you have, do the following
Edit the value for "PSpiceConfigFile" under following REG key
HKEY_LOCAL_MACHINE\SOFTWARE\Cadence Design Systems\Interchange\16.3.0\ProductConfiguration\Shared
Point it to modified PSpice.ini
