Resolve PI OfficeMail(TM).exe comes up as unknown publisher when executed in Officemail

Issue

The installer ( PI OfficeMail(TM).exe) does not have MS certificate and comes up as unknown publisher.
 

Cause

The PI OfficeMail(TM).exe is not signed properly and coming up as unknown publisher when executed.

PI OfficeMail(TM).exe is just a wrapper for signed installer.

PI OfficeMail(TM).exe contains piom.exe (PIOM.EXE is signed) + several other files:

Resolution

UPDATED: May 16, 2017
If you need the installer which has the certificate use PIOM.EXE, or if you are deploying the driver via Active Domain, use the MSI installer.

Otherwise the PI OfficeMail(TM).exe is still suitable installer.
