Cause

In this particular instance, SIM was pointing to the wrong installation drive reference in the registry.

SIM version: 8.0.53
 

Resolution

In order to fix this issue make sure the following regkeys have the proper drive reference:

HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\InstallDir
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\PackageRepositoryPath
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\PlatformInstallDir
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\Configuration\NsConfiguration\InstallPath
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\Configuration\ProductListings\Destination
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\Configuration\ProductListings\0\Source

Note: If SIM has another PL location specified under Settings, check under HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\Configuration\ProductListings\Current. If it is 1, then verify:
HKEY_LOCAL_MACHINE\SOFTWARE\Altiris\AIM\Configuration\ProductListings\1\Source for example
