The MuLab zip packages below contain all of MuLab.
Without a user key MuLab runs in Free mode, by inserting a user key MuLab switches to UL mode.
For the differences between MuLab Free and MuLab UL, click here.
When you cross the limits of MuLab Free, you'll regularly hear a soft noise.
MuLab UL user keys can be purchased in the MuTools Shop.

Download the MuLab zip package and unzip it to a new folder on your harddisk or USB device.
After you have installed the MuLab package, double-click the MuLab application file to launch it.
MuLab comes as a portable and self-containing folder. It does not install anything on your system outside this folder.
You can move the MuLab folder after you have installed it. You can even put it on a USB stick and carry your MuLab with you.
On OSX if you get the alert "MuLab can't be opened because it is from an unidentified developer", then control-click or right-click the MuLab.app icon and choose "Open". More info on OSX GateKeeper on this page.
On Windows 7/8, it may be better not to install the Mulab folder under the 'Program Files' folder, but rather in a non UAC protected folder like C:\Applications\Music\Mulab. This is to avoid access problems caused by Windows' UAC mechanism.
Alternatively you could try to run MuLab with "Run as administrator". To do so right-click the MuLab exe file.
If you have Microsoft SmartScreen enabled, choose "More Info" + "Run Anyway".
For all details on installation, inserting your MuLab User Key, updating etc, see this doc page.
