I'm trying to download an msi file automatically (actually via wget) and I get permission denied on windows 7. It worked find on vista. I tried downloading to a different name (not .msi), but then I get an error on calling WIN32 API MoveFile to rename the file to .msi What would cause this? How can I get around it?

where you downloading this file? Try turn off UAC or/and run wget with Administrator rights

I am a developer, and I'm writing this for third parties, I can't get them to change their security settings.

try with a runas /user: function to check if administrator rights may soluce the issue.
