# Signing with signtool.exe

Now that you have a PFX file you can sign your executables using SignTool from Microsoft. You can find more information on SignTool.exe here: http://msdn.microsoft.com/en-us/library/8s9b9yaz.aspx

## 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.
