-A launcher exe checks for updates from FTP.
-If a new update is found current exe is backed up, new one written
-Launcher ShellExecutes main.exe and ends

-Main.exe itself need to read/write local files.

If application is installed in Program Files than headaches of UAC begin. I can embed a manifest but how would the manifest embedded one be updated in the first place?

How do you deal with this (other than telling not to install under "Program Files", disable UAC alltogether)? TIA
