I have a laptop running version 93.0 (64-bit). It has removed the Trend Micro Toolbar & will not allow it to install. I have a different laptop running the same version of Firefox & it has no issues with the Trend Micro Toolbar. Please help me resolve the problem with the first laptop.

You can find the install location of a specific extension in the extensions.json file in the profile folder.

You can open the extensions.json file in a Firefox tab and search for this extension. The path field lists its install location.

Note that Firefox no longer allows external software to install extensions in Firefox by Sideloading add-ons via the Windows Registry, so you would have to install the extension yourself via the Add-ons website or allow the website to install their extension via "Tools -> Page Info -> Permissions" if Firefox doesn't ask for permission.
