We build our product from C and Asm source files, and ship all our .exe and .dll files signed with Authenticode.  In the past (before we starting signing our files), our customers could use a tool like ResHacker or Resource Tuner to change the app icon -- the icon that shows in Windows Explorer for an .exe file -- to something they like better than our icon.

The question now is how to support this capability in Authenticode signed file?  Or is it simply impossible?

If you modify the signed executable in any way, it will break the signing. One of the purposes of Authenticode is to protect software from any alteration.

Thanks.  Yes, that was my understanding but I wanted to make double sure before telling my customer that they were out of luck.
