The installer for the map maker/editor WONT work. Here's an image.
WRONG FORUM
I do have the same issue though... My boy wanted to play with the CW2 editor but Adobe Air is outdated, and Harman (https://airsdk.harman.com/runtime (https://airsdk.harman.com/runtime)) updates the air runtime now. Probably some incompatibility got introduced over time?
So "WRONG FORUM", as in? You didn't experience this with this CW2 editor installer?
I do... and I don't have a solution.
Does anyone else have a clue on how to solve this?
Adobe now removed the post on their forum how to resolve the issue.
I think the only solution now is to put your PC's clock back to 2017 or 2012 and attempt the install then.
Ah! read the "Custom maps section here:
