Signing with signtool.exe
Signing an Executable
Here is the command line call I use when signing an executable:
"C:\Program Files\Microsoft Platform SDK for Windows Server 2003 R2\Bin\signtool.exe" sign /f "C:\MY_CODE_SIGNING.PFX" /t http://timestamp.comodoca.com/authenticode /v /p MY_PASSWORD "Z:\path\to\my\application.exe"
Once the executable has been signed a Digital Signatures tab will appear in the file properties window.
When to Sign Executables
You will need to sign your LiveCode executables every time you create a new one using the Standalone Builder.
