Microsoft Teams won't update

[arteeh]

Brief description of your issue

When I ran winget upgrade --all with Microsoft Teams installed, it failed to update. It looks like the Teams installer doesn't work as an updater when Teams is already installed.

Steps to reproduce

• Have a non-latest version of Microsoft Teams installed. As of writing, for me that's 1.4.00.11161.
• Run winget upgrade Microsoft.Teams or winget upgrade --all

Expected behavior

Teams runs its installer of the latest version without errors, after which the latest version is installed and working.

Actual behavior

The installer downloads, starts, then exits with the following output: Installer failed with exit code: 1638.

The following installer log is written:

MSI (s) (90:E0) [09:38:04:808]: Product: Teams Machine-Wide Installer -- Configuration failed.

MSI (s) (90:E0) [09:38:04:808]: Windows Installer reconfigured the product. Product Name: Teams Machine-Wide Installer. Product Version: 1.4.0.11161. Product Language: 1033. Manufacturer: Microsoft Corporation. Reconfiguration success or error status: 1638.

Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

this was NOT fixed in that PR. I still have a bunch of duplicate packages that fail to update
