In Ergänzung zu jfheins:
Ich hatte das Problem ebenfalls.
Habe auch schon die setup.exe umbenannt, leider wird diese dann auch nicht gestartet.
Und was sagt GetLastError nun?
MfG Dalai
740 --> ERROR_ELEVATION_REQUIRED!
hab mal gegoogelt:
Being an administrator means nothing in an
UAC-aware operating system! You
do not run with the highest privileges even if you are an Admin here.
The CreateProcess Windows
API will always fail if a non-elevated application
under Vista/2008/Win7 attempts to launch another application whose manifest
requires elevation. GetLastError will return 740 (ERROR_ELEVATION_REQUIRED)
in this case.
