Sorry for the late reply, I am busy with house renovation and my old netbook was in another location. I just access to it a couple of days ago and this is the result:
- I could successfully install C2 release 275. Above stable versions cannot be installed.
- Latest NW.js I could install is the version v0.44.0 (Chromium 80) of 5th February 2020.
- Installing NW.js 0.44 (and few earlier versions), fails to install latest DirectX. I think the url it tries to grab does not exist anymore.
- The preview works on Firefox, but due to my little netbook computation power and perhaps weight of the browser (I believe), even the platformer template runs at 2 to 7 FPS.
- NWjs preview does not work instead. I can export the project in NWjs, but once launched the 32 bit version I get the same error of the preview.
I have installed DirectX End-User Runtime and Firefox ESR, the latter is the last update available for Firefox 32 bit version 52.9.0, but that does not solve the problem of the NWjs preview and neither improves browser performance (tested on the same platformer template).
The error message I get with NWjs is in Italian, but on the Internet I found other people have the same issue with other software, that translates as: "The procedure entry point could not be located in the dynamic link library kernel32.dll".
For what I can understand, that's the limit of XP architecture and basically NWjs in those latest versions doesn't work on XP.
Possible solutions could be to try to go back to earlier NWjs version and maybe install Chrome or other browser that might be a bit lighter weight.
Just to add more info, C2 'About' section mentions that is rendering with OpenGL 1.1.0, GDI Generic (no shaders) and recommends driver updates...
Overall, it's not great, but I can still use the netbook as emergency backup for little projects, especially for turn based game mechanics an such that does not need fast interactions.
Now, about the good part. Since the remote preview works, if there is an Internet connection available that can be shared, you can still use your mobile, tablet or other device to test your game. That is still something positive and useful as temporary backup and it's easier to work with keyboard and mouse instead of using C3 on mobile, that I could never even use to write a single line of code...
