user41541: How can i install old version of IDE, without uninstalling the other version?(How can i install several IDE version in same laptop).

user1576: Arduino.cc have a guide :
https://www.arduino.cc/en/Guide/PortableIDE
The gist is:

Download the desired version in ZIP format
Unpack the content in the zip file to a folder
Start the arduino.exe in that folder.

Remember that you have to place all libraries, board definitions in that folder.
The folder can be copied to another computer or a USB stick....
