As long as you have your license key and the electronic delivery download for your version of the compiler, there will be no issues installing it on a new system. If you need to get a copy of the electronic delivery download, just email Absoft support in the next few weeks and ask for the link to the download. In the subject put "Need link for electronic delivery package" and in the body indicate which OS (Windows, Linux, or macOS) and which version. For example, "I need the link to the Windows Pro Fortran 2022 download."
