Q: I'm having problems installing Mathematica on my computer (I can't find the license number, I can't find the password, the password doesn't work, etc). What should I do?
Please make sure to carefully follow the single machine instructions.

There have been a few cases where clients cannot run Mathematica after following the proper steps. However, the default license request form for students is for a version 8 license. The current student download is version 7. In at least one case the v8 license is not compatible with the student download.
THEREFORE: check the license request case - the request indicates near the top what was requested. If it's version 8 and the license key does not work, go to the license request form on the Wolfram website and make sure you pick a version 7 license in the drop-down list. This should fix the problem.
