Troubleshooting Sentieo Excel Plugin

There may be instances where the user is seeing this window during the installation.

Windows Project blue warning screen

You may see the below screen on rare occasions when you try to install Sentieo Office or Excel plugins

This screen is called “SmartScreen” and is part of Windows’ security features; It shows when you try to install a software for which Microsoft has not collected a lot of statistics from users’ computers of successful installations despite the warning message.

Sentieo certifies its software with Microsoft, but it sometimes needs to change instead of just renew its existing certificates. When we do this, the successful installation counter of SmartScreen resets to zero to our users start to see again the blue screen for a short while.

You can safely ignore the warning and click on Run Anyway to proceed with the installation.

If the security processes are more strict in your organization, you may need to discuss this with you IT personnel or you may not even see the Run Anyway button.

If you have the IT Admin authority, you can disable and enable the ability to override SmartSreen block by following the below steps: 

  1. Type Windows Security in windows search.
  2. Go to App & browser control
  3. Select the Warn option
  4. Now the Run Anyway button will appear
  5. Once the Plugin is installed then he can move back to Block.

Installation fails with error 0x80070659

If the installation of the Sentieo Excel Plugin fails with the error message below, the Windows profile configuration is preventing installation softwares like ours from adding new apps and addins to the system.

Windows is not set up by default to behave like this, except in rare cases such as some types of virtualized desktops offered by Amazon web services. If you are part of a wider organisation with an IT admin team, it could be that your windows profile was altered by the admin teams on purpose to block software installations.

The following steps show how to remove the bar. However, please be aware that this may violate your organization’s IT Policies, so we strongly suggest that you reach out for your IT admin’s assistance and only perform these steps under their supervision.

Steps for registry changes

  1. Download the CreateInitialRegistry.exe file from the below link.
  2. Save the file to any location.
  3. Run it.
  4. 2 files will be created in the same location
    1. DisableMsi.reg
    2. RevertDisableMsi.reg.
  5. Run DisableMsi.reg.
  6. Click on Yes on all the Message Boxes that appear.
  7. You should get the confirmation of a successful registry change (below). if not please contact Sentieo support.

  8. Now run the Sentieo Excel plugin installer again, and PLEASE REMEMBER to run RevertDisableMsi.reg after the installation is complete to revert your computer settings back to their original state.

Technical details about the registry change

The registry key DisableMsi controls if users can install software using Microsoft’s Windows Installer software installation tools; Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer

Our tool above creates a back up of the current value for DisableMSI (RevertDisableMsi.reg). We then ask the user to run DisableMSI.Reg file, which will set the value of the key to 0 (basically: disable the disablemsi setting). Then the user should run RevertDisableMsi.reg to return DisableMsi to its original state.

For further details on Microsoft Windows Installer and DisableMsi, please visit the below https://docs.microsoft.com/en-us/windows/desktop/msi/disablemsi
