Making it more readable (at the price of redundancy) will certainly reduce the number of support requests you get. In the end, when people got how it's done, they will do the refactoring by themselves.

Until something like that is available you could use one of the numerous windows UI automation and macro tools (they let you record mouse clicks and keyboard entries and play them back, also allow variables for input (to set export names, in your case). There are literally hundreds of those, mainly targeted for automated software testing, but they can be used for a task like yours.

Looking at the Clickteam tools is the best way to understand how C2 could reach almost 3.5 million downloads

Bought it, played it, love it so far! Also performance seems to be wicked good.

I ran into the same trap 5 years ago. I was used to software having multiple versions simultaneously on the same machine, and flip which version to use via an environment variable. I think C2 is not designed to work that way.

You are supposed to have one install on one machine. For a rollback you remove it and reinstall the older version. So the option you mentioned won't ever ask for an alternative location, it's just to determine if you want a "clean" reinstall or not.

Every game engine that I have ever dealt with had its share of problems. Unity has never been "problem-free". They are, like everybody else, in a permanent amorphous state of turmoil. If you think about it, it's only natural. They have better and worse phases, and not everything is their fault or even within their reach to change.

Interestingly, most of the issues I had with C2 were not with C2 itself, but adjacent (and still necessary) tech like NW.js, chrome or phonegap. In the end, if you hit a point in time where a C2 bug, a chrome bug, and a NW.js-f***up happen at the same time (think about the long, dark age of "the jank") it doesn't really matter who's fault it is, the outcome is the same.

Insofar all "X is better than Y"-discussions are pointless. Real engine agnostics expect to run into bugs everywhere

Nice find. Is it actively being maintained?

Have you asked your tester if the gamepad registers in browsers? (registering in windows does not mean much, a lot of stuff that runs in windows seems to be ignored by the browser gamepad API).

Yes.

It is specifically designed that way, so that you can (for example) have it on your home PC and on your laptop.

Licenses are not tied to a specific PC. So buying a new PC is no problem, you just put the license file onto the new one and you're good to go.
