Cause

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

Resolution

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

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
