Frequently Asked Questions (F.A.Q.)
  • Q. Does ZipCentral run on Windows 2000?
  • A. The current versions 2.02 and 2.06 will run on Windows 2000 with some limitations. To make ZipCentral run on a Windows 2000 system, the user starting ZipCentral needs administrative rights (i.e. logged on as Administrator or member of the Administrators group). These versions of ZipCentral were not designed to run on Windows 2000, therefore no support can be given on issues that arise from the use of ZipCentral on Windows 2000. Support for Windows 2000 is planned to be included in the next release of ZipCentral.

  • Q. Can I control ZipCentral with command line options?
  • A. No, currently there are no command line options included. Support for this may be added later on.

  • Q. Is ZipCentral compatible with WinZip and PKZip?
  • A. Yes. It should be compatible with all Zip-archives created in production versions of WinZip and PKZip.

  • Q. When I open a zip file, I can not see any files within it even though ZipCentral shows the correct number of files in the status bar. What is wrong?
  • A. You probably have an old version of some of the Windows system files. ZipCentral uses features included in a newer version of the file COMCTL32.DLL than the version included in the original Windows 95 and Windows NT 4 release. Follow the procedure below to check if you need to update your system:
    1) Click on the Start Menu and choose Find->Files or Folders.
    2) In the Named field, type "comctl32.dll".
    3) In the Look In field, type the path to your \Windows\System folder (usually C:\Windows\System or C:\WinNT\System32).
    4) When the file is displayed, right-click it to bring up a menu.
    5) Choose Properties and then click on the Version tab.
    6) If the file version is less than 4.70 (i.e. 4.00.950), you need an update to make ZipCentral run properly. In some cases, you may need an update even if the version is 4.70.

    If your system needs to be updated, download the
    Microsoft Windows Common Controls Update.
    When the download is complete, double-click on the 50comupd.exe file you just downloaded and follow the instructions to install the update.

  • Q. In the "Add files and folders to current archive" window, there are six buttons with no images and no text. Why is that?
  • A. Please see the answer to the previous question above.

  • Q. When I click on E-mail archive nothing happens. What's wrong?
  • A. Currently, this function does not work well with certain versions of Microsoft Outlook Express. It works better with the full version of Microsoft Outlook. If a solution is found, it will be included in a future version of ZipCentral.

  • Q. Why is the 'Virus Scan' menu item in ZipCentral 2.00 grayed out?
  • A. It is grayed out because you have not specified which scanning program to use. Click on 'Options' and then 'Configuration' in the main menu, then select the 'Program Locations' tab and enter the scanner you have installed.

  • Q. I have detected a problem with ZipCentral and I suspect it might be a bug. What should I do?
  • A. First, check that you are running the latest version of ZipCentral. The latest version number can be found on the What's New page and on the Download page on this website. The version of your copy of ZipCentral can be found in the About box. If you are running the latest version, please send a bugreport. Click here to find out how to write the bugreport. If you are not running the latest version, please download and install it and see if the problem still exists.

  • Q. Does ZipCentral run on Windows NT 3.51 or earlier?
  • A. No, it does not. Support for NT 3.51 will not be added.

  • Q. Can I get support on how to use ZipCentral?
  • A. Yes and No. Limited support can be obtained by sending an e-mail to No guarantees of reply can be given since all work with ZipCentral is done on my spare time.
