When installing my application, using a CAB installer, it fails to copy System.dll, mscorlib.dll and mscorlib.tlb and then fails to install.
I created a Windows Forms Application that I want to run in device running Windows CE 5.0. I followed the instructions here to create the .cab installer.
It turns out that I was having trouble with my network (I was executing the .cab installer directly from it). When I first copied the files to a local path it installed perfectly.
