How can I digitally sign MSI installer

[HarshSuman82]

I want to create an MSI installer file as digitally signed. I tried to put the event comment (CD "C:\Program Files (x86)\Windows Kits\10\bin\x64" signtool.exe sign /f "[Path Of pfx file]" /p "password" /t "[Path of MSI file]") at WiX toolset project's Post Build Event.
But I am getting an error "exited with code 9009". Please help me to find the solution for this.

It's recommended to use <Target Name="SignMsi"> in your wixproj file as described here.

This Insignia talks about external cabs but in my case, I don't have an external cab. It also doesn't mention a pfx file. I have to mention pfx file for signing the MSI file

If you don't have external cabs you don't need to include the SignCab target.

In that page, the content of the targets are just examples. Modify them as appropriate to your needs.
