Troubleshooting and uninstalling the Authenticator on Windows

Prev Next

Overview

This article covers common issues related to uninstalling the Beyond Identity Platform Authenticator when it is installed in the user context. Uninstallation behavior differs depending on whether the system installer or the Windows Desktop Login installer was used, and these scenarios typically do not result in problematic states.

MSI Missing

If some tool has cleaned up the Windows system installer files and the .MSI installer is missing, and or other uninstaller files have been cleaned up, the uninstaller may be lost, and the wizard will ask for a specific file, like C:\Users\BI-Admin\AppData\Local\Temp\0f57dfdd-e546-4562-8206-c7616636b093.msi.

Download specific MSI

You can download the latest installer from Beyond Identity (byndid.com). However, if you need a specific version, we retain the old installers for some time. They can be downloaded by fabricating the URL as follows:

The same applies to MSI files.

Once you have acquired the correct MSI file, you can rename it to match what the uninstaller asks. For example, C:\Users\BI-Admin\AppData\Local\Temp\0f57dfdd-e546-4562-8206-c7616636b093.msi is the missing file; you can rename the BeyondIdentity-2.79.1.msi to 0f57dfdd-e546-4562-8206-c7616636b093.msi and point its location.

Microsoft Removal Tool

Microsoft has a tool to fix/repair uninstallation. The Program Install and Uninstall troubleshooter helps you automatically repair issues when you're blocked from installing or removing programs. It also fixes corrupted registry keys.

Manual Removal

If pointing the uninstaller to a previously installed version's MSI file does not solve the issue, you may need to manually remove all the components before installing a new version.

Identify what to remove

Use the PowerShell command Get-WmiObject win32_product to get a list of installed software. Find the BI app GUID.

{6EDE4826-1964-464D-8601-C8507D3E1E4F}

Convert the GUID to an app identifier. For example, you can use the PowerShell function to do so:

Function Convert-GUIDtoPID {
[CmdletBinding()]
param(
#Accepts only GUID data type, to ensure Valid string format.
[Parameter(Mandatory=$True, ValueFromPipeline=$true,Position=0)]
[GUID]$GUID)

#Stripping off the brackets and the dashes from the GUID, leaving only alphanumerical chars.
$ProductIDChars = [regex]::replace($GUID, "[^a-zA-Z0-9]", "")

#1. Reversing the first 8 characters, next 4, next 4. Then for the latter half, reverse every two char.
$RearrangedCharIndex = 7,6,5,4,3,2,1,0,11,10,9,8,15,14,13,12,17,16,19,18,21,20,23,22,25,24,27,26,29,28,31,30
Return -join ($RearrangedCharIndex | ForEach-Object{$ProductIDChars[$_]})}

{6EDE4826-1964-464D-8601-C8507D3E1E4F} -> 6284ede64691d46468108c05d7e3e1f4

Now that we have both, we can find files and folders, and registry keys.

    Note: The bolded part will change per every installation.
    The file size will be an excellent hint to identify the correct MSI.

    Opening the file's properties and looking for the Details tab will confirm the file's identity.
