user account control - incorrect message

Hi!

when you run the installer in NSIS collected on Windows Server 2008 have a message like the picture. Our installer has a digital certificate, and the name of the company we see in the report. It is not clear that there is a "SetC02E.tmp", how to make a correct message or remove

Temp filename used by !packheader?

I can not reliably answer.
Installer script was prepared in a wizard "Venice IX" and nothing special was supplemented.
installer file is signed with a digital certificate my company.
