I am using an old version of the devkit and it works fine. I would like to experiment with the newest version so I renamed the c:\Espressif folder to c:\Espressif_
However when I try to run the installation of the newest devkit (Espressif-ESP8266-DevKit-v2.2.1-x86) I get the following message:
An old version of Unofficial Development Kit for Espressif ESP8266 was detected. Do you want to uninstall it ?
If I click No the new devkit is not installed
How can I have both installed ?

Have you tried renaming the directory and then running the uninstall. It will complain about not being able to find the files but might register that the old one is 'uninstalled', and then let you install the new one

You should be able to just work from the renamed folder. The install program doesn't do anything especially fancy - it just copies files into the folder structure.

I have tried install the development kit on 2 laptops but same problem. Please check my video.
