The most common problem that causes users to be unable to open this file is an incorrectly assigned program. To fix this in Windows, you need to right-click on the file, in the context menu, point to the "Open with" item, and select the "Select program ..." item in the drop-down menu. As a result, you will see a list of installed programs on your computer, and you will be able to choose the appropriate one. We also recommend checking the box next to "Use this application for all ZIP files".
Another problem that our users also encounter quite often is that the ZIP file is corrupted. This situation can arise in many cases. For example: the file was downloaded incompletely as a result of a server error, the file was damaged initially, etc. To fix this problem, use one of the recommendations:
