How do I Remove These Rex.Rainbow Files?

Is there a way to remove these files or any other file that stops the game from opening so I can at least open it to see if maybe they can be substituted with something else?

I have a few games that I put a lot of work into that I would at least like to try to save if I can.

Thank you in advance for your help

If you made them in c2, you can open them in c2.

Remove or replace any use of the plugins, and then you can open in C3.

You can have third-part Construct 2 add-ons in Construct 3 by asking their authors to port them using our SDK.

Otherwise, check the Exchange Addon or this dedicated forum (and this topic) to see if a port already exists.

Finally you can try this beta converter.

Once you have a Construct 3 version of the add-on, you can install it using the add-ons manager.
