I can't use the ia64-version of devcon.exe on my Windows7 professional x64 (AMD CPU). error message tells me, that the version of this applcation is not suitable for this version of windows and I should check whether I need to use a x64 or x86 version of this application. The x86 version starts correctly, but all operations (remove, restart, disable etc) fail. Running from a command line with full privileges. Any ideas how to solve this?
