The very first thing, I will suggest to check for duplicate systems. There is default query (ePO:Duplicate systems). Please run and check for duplicates.
If not duplicates then under system details, is the issue with VSE not listed or all the other products.
If the issue is with only VSE then please look for plugin value (HKLM=>Software=>Network associates=>Application plugins=>VSE=>Plugin flag). If the value is non-zero then please change it zero, restart the framework service and initiate ASCI from the client machine.
