Using Mulab on a new PC

[Kazene_Ame]

I bought a new PC recently and don't know how to transfer my liscence over from my old one.

1) Install MuLab on your new computer
2) Insert your MuLab user key into that newly installed MuLab
3) If you gonna give / sell your old compu to someone else then remove your user key from the old MuLab install
(MuLab menu -> Insert User Key -> Remove it there and click OK. It will ask "Remove user key?" Click Yes)

Note that if you have a MuLab 7 user key it won't work for MuLab 8.
You can upgrade your user key via http://www.mutools.com/shop.html
Or you can download the relevant legacy version from http://www.mutools.com/mulab/legacy-versions/

Ok there was some double posting issue and i accidentally deleted the wrong post. Anyway here is the answer you asked for:

I'm unable to find the E-mail containing my user key, is there any way for me to find it elsewhere?

It's important that you properly and securely store your user key so you (and only you) can retrieve it whenever you need it. If you cannot retrieve it then email MuTools' infodesk:
Note that it's not always possible to instantly lookup your user key, so in the future please make sure you properly and securely store your user key yourself.
