Hi Raja,

Thanks for using the BizTalk Software Factory!

Did you try a clean install of do you have v1.6 already installed?

Kind regards,

I don't have any previous versions in that box. I tried the fresh version 1.7

Did you install the prerequisites GAT and GAX?

It looks like it is missing an dependency in the installer, which is referring to assemblies that should be installed with the GAT/GAX install.

Kind regards,

Thank you Jean-Paul. As per your suggestion, installed the GAX that fix my issue.
