Unable to initiate Mage's Initiation in GOG Galaxy

[Dungy]

I have attempted installation of game twice, but there seems to be an error with running game in GOG Galaxy. On startup I immediately receive the following error. Seems to be some problem with communication between adventure game studio and GOG Galaxy achievements. I am unable to proceed.

Loading game failed with error:
Script link failed: Runtime error: Unresolved Import
'AGS2client::Setachievementacheived^1'.

The game file may be incomplete, corrupt, or from unsupported version of AGS

You may need to update the Visual C++ Redistributable for Visual Studio (2015?) via the official Microsoft site.

This is with the Windows version?

It sounds like the files may be corrupt. Have you tried verifying them and/or reinstalling?
