How to Fix VT Transaction ad-ins in Excel

VT Transaction+ stopped working correctly with Excel after a recent Microsoft Office/Microsoft 365 update. The issue appears to be related to the VT Excel add-in or Office compatibility. I have confirmed that Microsoft Office/Excel is installed as a 32-bit version, which is the version recommended by VT Software, as 32-bit Excel is not compatible with VT add-ins. I have uninstalled and reinstalled Microsoft Office three times, but the issue persisted after each reinstall. I also removed and re-added the VT Excel add-in multiple times; however, the problem remains unresolved. The system continues to display the following error message: System Error &h80004005 (-2147467259)

    Hi @Oas Acc

    The message System Error &h80004005 (-2147467259) is a general COM/Automation error, also known as E_FAIL. With Excel add-ins such as VT Transaction+, it may indicate that Excel cannot initialize or communicate with an add-in component, DLL, database driver, or required registry entry.

    As Excel and the VT add-in have already been reinstalled, please also work through the checks in VT Software’s official Add-ins missing troubleshooting guide.

    Although the guide is not specific to error 80004005, it will help confirm that the VT add-ins are enabled, have not been disabled by Excel, are installed in the expected location, and are not being blocked by antivirus software

    Once you have completed the checks, close Excel completely, reopen it, and test the VT function again to see if it works.

    Hopefully this helps resolve the issue. If anything is unclear or the issue persists, feel free to reply below.

    Since Office has already been reinstalled three times and the VT add-in has already been removed and re-added multiple times, the next supported path is to isolate whether the failure is caused by the add-in itself or by Excel/Office compatibility.

    1. Start Excel in Safe Mode.
      • Press Windows + R.
      • Run: excel /safe
      • If Excel opens, confirm Safe Mode appears in the title bar.
    2. If Excel works in Safe Mode, disable add-ins one at a time.
      • In Excel, go to File > Options > Add-Ins.
      • In Manage, select Excel Add-ins or COM Add-ins, then select Go.
      • Clear one add-in, select OK, then restart Excel normally.
      • Repeat until the failing add-in is identified.
    3. If Excel starts after the VT add-in is unchecked, the issue is with that add-in.
      • Leave it disabled temporarily.
      • Check with the add-in vendor for an updated version that supports the current Office build.
    4. If Excel does not start in Safe Mode, the issue is not caused by add-ins.
      • Run an Office repair first.
      • If repair does not help, uninstall and reinstall Office.
      • If the issue still continues, install the latest Windows and Microsoft updates so device drivers are current.
    5. Confirm Office bitness matches add-in requirements.
      • 32-bit Office is the correct choice when an organization depends on 32-bit COM add-ins with no 64-bit alternative.
      • 64-bit Office cannot load 32-bit binaries.
    6. If the VT add-in is a COM add-in or uses older VBA/API components, compatibility after an Office update can still break even on 32-bit Office.
      • Existing 32-bit COM add-ins continue to be the best fit with 32-bit Office.
      • If the add-in vendor has not released an updated build for the current Office version, Excel can continue to fail until that add-in is updated.

    Based on the described symptoms, the most likely supported conclusion is:

    • If excel /safe works and Excel fails only when the VT add-in is enabled, the add-in is the cause.
    • If excel /safe also fails, focus on Office repair and Windows/Microsoft updates.
