I have several computers that test installing a program that is hosted on a network drive. Due to the nature of my system (which is very complex) the setup file is being executed from Cygwin. So up until now it just started Cygwin and executed the setup:
It works perfectly on all flavors of Windows up until Windows 7. Recently I got Windows 8 and Windows Server 2012 but the same trick does not work anymore on these platforms. Now I get "Permission denied" when running the setup from Cygwin. This most certainly has to do with some new security policy in Windows.
I should note that I can run the setup from cmd but the problem is that I have to do it from Cygwin. I should also note that UAC on those machines is deactivated. Any idea on how I can work around the permission issue?
