Installed over the Peppermint partition. Most apps still work, settings were widely recovered and it runs fine.
One exception was Chrome. It needs an old version of the libudev (libudev0 instead of libudev1).
For 64Bit version, which I can highly recommend, you need to install the old version of the libudev until a fix for Chrome is out.
Try this:
