Hello, how are you?
My name is Paloma B., I am very happy to be able to try to help you in the best possible way.
This is an open community, whenever you need you can share the problem so that possible repairs are suggested.
Could you give more information about the problem, please?
What kind of error are you facing with this program?
Is there any specific reason to use this program to unzip files?
If not, I think 7-zip can help you, it's an excellent tool for unzipping.
