I have successfully signed my EXE using my COMODO certificate. I've confirmed (using file properties) that it has the digital signature. But when I run the program from a network folder, Windows7 tells me "We can't verify who created the file. Are you sure you want to run this file?"

The network folder is located on my home network, on an XP machine.

I have tried:

> signing all the DLL's related to the program.

> Installing the certificate. From the file properties window, digital signatures tab, signature list - details button... view certificate button... install certificate button. Accepted all the defaults from the wizard and received message that the import was successful.

> Rather than signing the EXE using SignTool, I created an SB installation program which tells me during compile that the file was properly signed.

Any ideas what I'm missing?
