That's strange. I haven't seen that happen before. I used 7-Zip to make the zip file. I don't know what you're using to unzip it, but you may need to use a different program to unzip it. The path too long part, I don't know. I know Windows has a limit on path length. But since you tried different locations, I'm not sure. It may be related to the program you're using to unzip it.
Edit:
I looked into the path too long part and if you're using the built in Zip package handler in Windows, it may not work because of the deep nested folder structure. 7-Zip allows for deeper paths than Windows default zip handler. So try 7-Zip to unzip it.
I hope this helps.
