Sometimes it’s not possible to install Mu because the computers you have available are locked down by somebody else.
Perhaps you find yourself running a workshop in a library or your school’s network administrator is more likely to say “get off my lawn” than “let me help you with that”.
Don’t worry, thanks to the remarkable work of 14 year old Josh Lowe, you can run Mu from a pendrive (those dongle-thingamabobs for storing files that you plug into the computer’s USB port).
This technique should work on both Windows and OSX.
When you launch an application it needs to be read into the computer's memory in order to run. The hard drives of computers are many times faster than pendrives when it comes to this. As a result, it may take many seconds for Mu to start up after you try to launch it. Precisely how long depends upon the quality of your pendrive and perhaps the age of your computer.
In any case, patience is the name of the game here. Once Mu is up and running, it should work as fast as if it were installed in a more conventional manner.

There is also advice on Microsoft’s website for finding whether you are using 32 or 64 bit Windows.
Once you’ve downloaded the correct zip file, extract it (right click, then
select extract) onto the already attached pendrive. When you plug the pendrive
into a locked-down computer, navigate to the folder on the pendrive where you
extracted Mu and double click on the
Launch Mu.bat file to start. It may
take some time for Mu to launch because of the relative slowness of
Sometimes, depending upon the machine you’re using, Windows may say that it is protecting your PC from an unrecognised application.
The solution is to click on the “More info” link:
Then click on the “Run anyway” button.
You simply need to download the existing OSX installer, copy it
onto the pen drive and double click it on the pendrive. However, instead of
mu-editor icon to the “Applications” folder, you should simply
double click it and Mu should launch. As mentioned before, this may take some
time and, when run for the first time, OSX may ask you to confirm you want to
