Vista - Signed Exe is being blocked by Vista

I have a digitally signed program that is being blocked when run on a
particular Vista Home Premium machine. The same program runs fine on
other machines, it's just this one machine. Each time the user tries
to run the program they get the "Open File - Security Warning" message
dialog. The Publisher is listed (so it's not unknown).

The problem us that because Vista is seeing the program as "bad", it
runs in a lower priv level than is needed to run the program (i.e.
access to reg keys and profile information) and the program does not
work,

How do I get this program off the "bad list", or get the Publisher
back on the trusted list?

Hello,

May be your autivirus program blocked it, u can check it or remove the bad
list from the antivirus program.

I thought I would update on this issue.

Our application has been updated to include a proper UAC manifest
(asInvoker) for Vista, as well as the digital signature, which it
already had. These changes did not fix the Open File - Security
Warning prompt that our client gets when trying to run the
application.

We renamed the folder the application is installed in, as well as the
application itself and still the warning appears.

We had the client turn of UAC and the prompt still appeared.

We also had the client export his registry as text. In his registry
we found a VirtualStore key under HKEY_USERS\<user id>\Clasees\Software
\Machine\VirtualStore\<company>\<product>. Deleting this key made no
difference,
