Unable to repair or uninstall Ablebits add-in

When trying to install a new version

If you try to install a new Ablebits add-in for Excel when an older version of the product is already installed on your machine, you may face a problem with Windows Installer Package. In the majority of cases, this may happen because the .msi file was lost or the add-in file was deleted or renamed. First of all, try to uninstall an old add-in version via Control Panel instead of Apps & features in Windows 10. If for any reason it doesn't help and you still receive an error message, please follow the troubleshooting instructions on this page.

Uninstall via Control Panel

  1. Close all Microsoft Excel files.
  2. Go to Start and open Control Panel.
  3. Click on Programs:
    Pick Programs
  4. Pick the Uninstall a program option:
    Uninstall a program
  5. You will see a list of all installed programs. Find the add-in you want to uninstall and double-click it.
    Click Yes in the dialog window:
    Are you sure?

If you can't remove the add-in via Control Panel, look at the screenshots below, find the message you are seeing, and follow the instructions.

Remove AblebitsLoader.exe before uninstall

Please look through the screenshots and if you see your message among them, remove the AblebitsLoader.exe file from installation folder and try to uninstall the add-in via Control Panel again:
Installation source is not available.
Did not finish as expected.
Windows installer package problem.

  1. Browse to the add-in's installation folder:
    %LOCALAPPDATA%\Add-in Express\Ultimate Suite for Microsoft Excel
    %LOCALAPPDATA%\Ablebits\Ultimate Suite for Microsoft Excel
    C:\Program Files (x86)\Ablebits\Ultimate Suite for Microsoft Excel
    Another folder you have chosen while installation.
  2. Delete the AblebitsLoader.exe file and try to uninstall an add-in again. If this doesn't help, remove an add-in from the Registry Editor.


In the start menu in "Company Portal" Ablebits Excel Suite" has a checkmark "Installed." However, it is not installed on my computer so I am unable to uninstall or reinstall. HELP!

I tried to uninstall the program, but it keeps saying "There is no PREVIOUSTIMESTAMP for uninstalling the product. Try run setup.exe as Administrator"
Lemme come clean first, I deleted the Timestamp from registry and now I regret it. Please help me...

I am getting the following error when trying to install:

"There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor."

Please advise
Thank you

Hello Steve,

Sorry to hear that you are having difficulties with the installation.

Most likely, you haven't uninstalled the previous version of the product completely. Please try to clear the registry as described here.

Then download and install the latest version of Ultimate Suite anew using this direct link.

If you still have any difficulties, please contact support@ablebits.com for further assistance.
