Vista puts "Not responding" box over my application always

When my application(32bit) about to launch in Visat x64, it draws the border over my application and says "Not responding". This is not happening in Windows XP. Also the time period that taken by application differs from XP and Vista x64. Vista takes more time to load than Xp. Some one please help me out.

if i were to take a shot. id say you're missing dll files.

@Antihiatus

No possiblity to miss dll files. I am installing my product using msi installer, same like XP. In XP everything is fine. But here vista i am getting "not responding" for 10 or 15 seconds when it is about to launch and finallt it is loaded. While asking Username and password wizard it is fine though. After verification of username and password, while loading the product only this happens

Well sometimes when I install programs they don't come with all the dll files.

hmm, maybe you need more ram?
