I signed up and downloaded the Math Kernel Library 2017 for Windows under the Community Licensing. However, I get the following error message when trying to use the serial number during the installation process:
"Activation rights do not allow this software to be installed. This could be due to expired subscription or incompatible serial number."
It's possible that I installed this library once before -- on a different machine. I don't really remember. I know that I looked into installing it once, maybe back in 2014 (?) but don't know that I ever actually did.
If this is the problem, how do I "deactivate" the old copy? The machine it would have been is long gone (no longer works).
BTW: I didn't try using the licensing file trick. Let me know what to do. Thanks!
