Installation and Licensing
All Ansys Optics products utilize the Ansys licensing system. Within this category, you will find instructions on how to install your software, and how to activate your license. Most of the guides in this category or product-agnostic, but there are certain topics which may pertain to only 1 or 2 of our products. In that case, a tag with the product name is added to the top of the article. If you cannot find your answer in our guides, or need other help with your install, please don't hesitate to reach out to us via the Ansys Customer Support Space (ACSS). Please note, users at academic accounts should use AIS instead of ACSS.
