Vista - Elevation of Program Rights under Local User Account

I am in need of advice on how to approach this. I've install a program under
administrator account to be use on a local user account. I've already gave
the user, power users rights from the Local User and Groups under Computer
Management.
Now here the fun part..
Under the Local User Account, when the user double click to execute the
program, is seems the the Application does launch, but I still get an the
error message and that says "Windows is looking for a solution". I have also
tried granting permission of the application from the registery editor as
well. Is there another permission where the UAC have access to.

Thanks.
