If you’re trying to run Pencil2D and an error pops up about Qt5Widgets.dll not being found, you are not extracting it correctly, plain and simple. Your project should open fine when you correct that issue. You need to:
- Download the zip.
- Extract all of the contents of the zip to a folder. Usually people put this in C:/Program Files but you can have it basically anywhere.
- Go into the extracted folder and run pencil2d.exe inside of it. Make sure you are not going into the contents of the zip file you downloaded. In fact, it’s best if you just delete the zip file as soon as you get it working so you never confuse it with the actual application folder.
If this still doesn’t solve your issue, you can take a look at this guide, which contains some more advanced troubleshooting tips for Windows.
