try to copy the ----- file named "STRGXI2.dll" found in the -------- package and replace the existing file in "C:\Program Files\Common Files\AspenTech Shared" and/or "C:\Program Files\Common Files\Hyprotech\Shared" then run the license validation from "C:\Program Files\Common Files\Hyprotech\Shared\SLMLicenseProfiler.exe", load the licence by selecting the license location then press load.
That should solve the problem.
