preparing for an eventual roll back to Arduino IDE 1.8.12

The Arduino IDE 1.8.13 has been released.

Though I don't trust freshly released versions.
How would be the easiest way to make some kind of backup of Version 1.8.12 that in case the new version 1.8.13 os not working properly I can make an easy roll-back to version 1.8.12.
Of course I can de-installate and re-installate. But I'm looking for an easier way.
Would a copy & paste work properky?

Or is it possible to have two versions installed in parallel?

best regards

Stefan

If you make a "portable" install of Arduino it will be completely isolated from your system. Search for details on the Arduino website, it's easy. You can have as many portable installs as you want.
