I was able to download, install and use the Express License. My organization has the educational licenses and we access them through a server. But it doesn't work with the Parallels Desktop app. Do you know if I need special configuration to make it work?</P> Wed, 06 Aug 2025 05:29:56 GMT https://forums.autodesk.com/t5/flexsim-installation-licensing/license-server-not-working-with-parallels-desktop-mac/m-p/13755524#M379 murzuaAZJZD 2025-08-06T05:29:56Z https://forums.autodesk.com/t5/flexsim-installation-licensing/license-server-not-working-with-parallels-desktop-mac/m-p/13763445#M380 <P>In the past it wasn’t allowed to use a standard license on a virtual machine, because there is a possibility, that such a license can run simultaneously on more physical machines.
