I am trying to reinstall the Arduino IDE on my computer (Win 10) which had earlier used the same Arduino IDE version 1.6.0 (portable). I am now facing the issue of opening the IDE even.
This problem started when i installed the version Arduino 1.8.1 (non-portable). For certain reasons i want both the versions on my computer now. I have uninstalled 1.8.1(non-portable) and have put the portable version 1.8.1 in appropriate file directories. 1.8.1 exe runs perfectly but 1.6.0 exe still doesnt. Are there any ways to do so?
