Suggestion: Wouldn’t it be nice if the Introjucer could auto-generate a Windows Installer Project + and has the ability to add a certificate for code signing the binary?
BTW i have no idea how to do that 
It’d be great - unfortunately I have no idea how to do that either!
I sign my projects in VS2010.
Create a post build event (Project > Properties > Build Events > Post Build Event):
SignTool sign /v /ac %CROSSSIGNCERTLOCATION% /f %CERTLOCATION% /p %CERTPASSWORD% /t http://timestamp.verisign.com/scripts/timestamp.dll $(TargetPath)
Of course the three macros must resolve to the location of the actual certificates.
Thank you,
