a. Have you tried opening (extracting) the zipped folder on another computer? Does it extract fine without any errors?
For now, I’d suggest you to uninstall the 7zip and Uniextract software and re-install the same and check if that fixes the issue.
Also, make sure that the compression format is supported by 7zip or Uniextract.
If the above steps do not work, create a new user account and check if you can extract the compressed files without any issue.
Follow these steps to create a new user account:
1. To open User Accounts, click the Start button, click Control Panel, click User Accounts and Family Safety, and then click User Accounts.
2. Click Manage another account. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
3. Click Create a new account.
4. Type the name you want to give the user account, click an account type, and then click Create Account.
If, in the new user account you’re able to extract the files without any error message, it indicates that the other user account is corrupted.
You may fix the corrupted user profile.
Your user profile is a collection of settings that make the computer look and work the way you want it to. It contains your settings for desktop backgrounds, screen savers, pointer preferences, sound settings, and other features. User profiles ensure that
your personal preferences are used whenever you log on to Windows. If you tried to log on to Windows and received an error message telling you that your user profile might be corrupted, you can try to repair it. You will need to create a new profile, and then
copy the files from the existing profile to the new one.
