If you use the windows search tool for "License Utility" and press enter [assuming you only have one such licensing application on your system]....this will open the Solid Edge License Utility, where you can make your selection to "I have an Academic Code"...enter your license code & name of school....and Solid Edge should now run, as expected.
@verdos Mike Brown sent me the 12-digit code that you received. We see the upgraded code had an error. Mike and I will send you your correct ST8 code via email now. Mike is working with Siemens IT/web team to correct the ST8 academic code generation.
