Okay, here's my setup.
I have a c# app working perfectly on all 32-bit Windows XP-Vista-7 machine. I already have a verisign PFX to support the ClickOnce deployment and is using Atalasoft DotTwain 8.0 as the 3rd party scanner helper.
When I publish my application, I choose "Any CPU" as the Platform target. When I try to make it run on a Windows 7 64-bit Home Premium, my application crashes after the installation.
I tried re-publishing the work on a specific x64 platform but still failed.
Any ideas on what i'm doing wrong here? thanks so much~!
