@LexiaFira Honestly since Microsoft already stopped supporting and updating Windows 7 since almost 1 year ago, it’s hard to tell to what extent will things keep working. Even Pencil2D new versions, at some point will be forced to stop supporting Windows 7 and 8 since the base technology Pencil2D uses is always deprecating operating system, so if we want to keep up to date to avoid critical bugs, we might need to stop said support, but that’s only speculation for now.
We hope you can make it work on your laptop, otherwise let me know and i’ll link other potential animation apps you could try that have synergy with Pencil2D.
