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.

I used this command line call successfully on Windows 10 with a digicert certificate:
"C:\Program Files (x86)\Windows Kits\10\bin\x86\signtool.exe" sign /f "C:\Path\To\Cert.pfx" /tr http://timestamp.digicert.com /td sha256 /v /p PASSWORD_HERE "C:\Path\To\Application.exe"
