Vulscan failing to run (User does not have admin rights)

Hello,

In our organization we have custom shortcuts that run a vulscan against a patch group and repairs any patches found in that group.  The command is below:

"%PROGRAMFILES%\LANDesk\LDClient\vulscan.exe"  /repair group=21186 /showui=true

None of our users run as admin, and this shortcut always works for them.  I have one user however, who gets the following message when attempting to run this shortcut:

Current user does not have administrator rights, elevating rights
Current user does not have administrator rights to run Vulscan.
Please contact your administrator.

This is vulscan.exe version <8.80.2.85>.

Any help?
