Used at our University as a teaching tool as they provide free student & academic licenses for application usage. Vendor EXE, freely available to download, supports silent all user switches. If anyone ever wishes to license it, a "gamslice.txt" files can be obtained from the vendor & added to %ProgramData%\GAMS & the application will autodetect the license in place.
The General Algebraic Modeling System is a high-level modeling system for mathematical optimization. GAMS is designed for modeling and solving linear, nonlinear, and mixed-integer optimization problems
GAMS uses a non-standard format in their version number (GAMS 47.3.0) which includes letters. This non-standard format prevents our current detection methods from working properly and we are unable to support products that require file version detection at this time.
Please upvote the following idea to enable support for file version detection: https://ideas.patchmypc.com/ideas/PATCHMYPC-I-1591
You could also reach out to the vendor and ask them use the correct version format.
