I had the same issue. I am building the application from a thumb drive on numerous computers and believe this is the cause.

I found success with the "sn -i [comodo].pfx VS_KEY_xxxxxxxxxxxxx" method. I did the following steps:

1. Run "Developer Command Prompt" as administrator (found in Start->All Programs->Visual Studio->Tools)
2. Navigate to your key directory (for me this was the root of my project directory, not the solution directory)
3. Execute "sn -i mykey.pfx VS_KEY_xxxxxxxxxxxxx" (mykey.pfx and VS_KEY_xxxxxxxxxxxxx are both found in the build error message)
4. Enter the password if required

When I tried this without running "Developer Command Prompt" as an administrator, I get the help display text when running "sn -i mykey.pfx VS_KEY_xxxxxxxxxxxxx" and it does not work. The trick was to make sure I ran the develop prompt as an administrator.

For context, I am using VS Community 2013.5, Window 7 x64 Professional, and NET Framework 4.7
