#1412 Unknown publisher - block installation

[hirrsson]

Hi

I just downloaded the file and wanted to install it.

I get the following error message:

Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App:
SetupGCSM-4.2.1.msi
Publisher: Unknown publisher

Any chance to add the publisher to the installation file so it can be installed?

thx
