M9 Docs   MuLab App Installation

MuLab App System Requirements

  • Windows Vista and up.
  • MacOS 10.9 and up.
  • Good soundcard/device with good driver and with at least 1 stereo output.
Not necessary but recommended:
  • Powerful multi-core CPU.
  • Minimum graphics space of 1920 x 1080 pixels.

Download the MuLab App zip package and unzip it to a new folder on your harddisk or USB device.
Please make sure that the complete folder path towards the MuLab Plugin folder does not contain any special characters, except for plus, minus (hyphen), underscore, round brackets and square brackets.

After you have extracted the MuLab package, double-click the MuLab application file to launch it.
On Windows that's MuLab.exe, on MacOS that's MuLab.app.

MuLab App comes as a portable and self-containing folder.
It does not install anything on your system outside this folder.
You can move the MuLab App folder after you have installed it.
You can even put it on a USB stick and carry your MuLab App with you.


It may be better not to install the Mulab App 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.

The reason for this is that MuLab stores your user settings in a couple of files in MuLab/User/Settings. The good thing about that is that your MuLab installation is easily movable, and can be put on your USB stick for example. Another advantage is that you can have multiple independent MuLab installations on the same system, for example different versions of MuLab. Therefore it's best that the user settings are store inside the MuLab folder and thus this folder must be writable.

If you have Microsoft SmartScreen enabled, choose "More Info" + "Run Anyway".


Unfortunately Apple has chosen to make MacOS very unfriendly towards non-Apple software.
That's obviously for commercial reasons.
MacOS does not give the user easy tools to manage the security of downloaded apps.
Hence it takes some actions to enable the downloaded MuLab and make it run on MacOS.

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 MacOS GateKeeper on this page.

MacOS Sierra and up:

Due to some new protection in MacOS Sierra called 'GateKeeper Path Randomization' it may be that on launching MuLab it alerts "Can't find app sub-folder" or "Folder is not writable".
To solve this MuTools has made a little tool called "Quarantine Remover" to remove that default Apple quarantine.
The Quarantine Remover is included in the downloaded zip package.
How to use it:

  • Launch Quarantine Remover, eventually via right-click -> Open
  • Drag-drop the MuLab.app file onto the green window area
From now on, MuLab can be launched normally.
Luckily this process to get MuLab started only has to be done once per downloaded MuLab.
