A website https://expertcare.medcentral.org requires IE and an Add-on. This add-on requires administrative privileges to install. I would like to deploy this add-on as a post-installation task, but am completely baffled by the whole process.

Has anybody scripted out IE add-on deployment?

After installation the add-on manually, I find two files in the C:\windows\downloaded program files directory. They are:


Previous research indicated that running

regsvr32.exe IETools.dll

would accomplish an installation of the add-on, and so I set up a scripted install that had that operation set up as a post-install task.

Navigating to that site still prompted for installation of the add-on. I clicked yes to allow installation and was prompted with administrative credentials.

I closed the browser, re-ran the command, and found that I wasn't prompted when re-opening https://expertcare.medcentral.org

Anyhow, has anybody had experience with this business? Seem to be a huge pain, and after throwing myself at this problem now several times over the last 6 months or so, I haven't been able to uncover any productive research. Any help is appreciated.

I went to the web site initially and downloaded the software from the web site.  Afterwards, I unregistered the DLL using the below command, then made a copy of the two files before deleting them from the "C:\Windows\Downloaded Program Files" folder.

REGSVR32.EXE /u "C:\Windows\Downloaded Program Files\ietools.dll"

I went to the web site afterwards and was prompted to install the software, so the removal was successful.  I copied the two files back to the "C:\Windows\Downloaded Program Files" folder and registered the DLL with the command below.

REGSVR32.EXE "C:\Windows\Downloaded Program Files\ietools.dll"

I returned to the web site and was not prompted to install the software, so it seems that it is functioning properly after a "manual" installation.
