Hi, I've just run the setup64.exe following a procedure I use to defeat UAC's privilege elevation based on the "setup" substring. That is I renamed it to cygpkg64.exe and ran it as a non-privileged user.
I've noticed that this no longer defeats UAC, at least with 2.795 build of setup64.exe. Based on my limited understanding of .exe.manifest files, I believe the problem should be related to this change to Cygwin setup: http://sourceware.org/cgi-bin/cvsweb.cgi/setup/setup.exe.manifest?rev=2.4&content-type=text/x-cvsweb-markup&cvsroot=cygwin-apps with changelog excerpt: * setup.exe.manifest: Set processorArchitecture to "*". Add explicit requestedExecutionLevel for 64-bit compatibility. Am I correct?
