I have created a Visual Studio 2010 setup project, which contains two executable files and some additional xml files. The overall size is about 2mb and installing is just a simple copying to ProgramFiles with adding icons to desktop and start menu.
But it takes about 30 sec to install in fast computer and about 3-4 min in slow laptop. What could be the reason of it?
Use ProcessMonitor to see what is taking so long on the laptop compared to the fast pc. My guess is that old hardware (eg HDD, Ram, etc) is the reason.
