Long startup times and missing background images

[Mexxi]

I finished my installer and sent it to several customers, who ran into a lot of problems. Many reported a long startup time of up to 10 minutes. The only thing that the installer does before starting up, is checking the registry for a file path and then looking for an executable in that path.

Furthermore, many have reported missing background images, resulting in white screens only with text. This was reported for systems sporting several types of Vista and Windows 7. I myself tested the installer on XP x86 and Vista x64 and had no problems. What could have gone wrong?

Are they running anti-virus software? If yes ask them to disable on-access scanning.

thanks for your answer. actually i found out that vista's and windows 7's UAC created the lag, because those scanned the setup file in the background. just the more reason to include my requested option to keep the files in a seperate archive as the installer and not putting it all into the same executable.
