Adding the Live Communications Active Directory Tab in Windows 7

A few months ago, we ran into a roadblock where I work — attempting to install the Live Communications snap-in for Active Directory works fine in Windows XP, but in the move to Windows 7, it simply wouldn’t install, erroring out at every attempt.  Today, I finally figured out what we needed to do.  If you’ve faced a similar problem, read on.

We use Microsoft Communicator to make communication all over the company more efficient.  We’re the ones people look to when they need an account, so if we can’t access the Live Communications tab in AD, that whole process grinds to a halt.

When trying to install directly from the LcAdmin.msi in Windows 7, even if you’re the proud owner of an account with administrative privileges, you’re likely to see this message:

error 27711. error ‘0x80070005’ stopping service ‘winmgmt’.

At that point, the installer pauses, rolls back changes, and exits.  For some reason, administrative permission to run the installer itself doesn’t get extended to the scripts that run subsequently as part of the installation.  To resolve this, you need to run the MSI from an administrative command prompt which, strangely enough, passes along the permissions correctly.

To do this, go to the Start Menu in Windows 7 and type “cmd” (without the quotes) into the Start Search field, but do NOT press Enter.  The search will bring up “cmd.exe” above that.  Right-click it and choose “Run as Administrator.”  A DOS command prompt window will open with “Administrator: C:\Windows\System32\cmd.exe” in the title bar.

Now, with the LcAdmin.msi file on your local system, navigate to its containing folder through the command prompt (cd c:\[folder path] should do the trick) and once there, type in LcAdmin.msi and press Enter.  Follow the prompts to complete the installation, and now in Active Directory for each user you should have the Live Communications tab, where you can assign SIP addresses, designate a server or pool for the account to connect to, and so on.

It’s hard to say why oddities like this pop up to slow us down and irk IT professionals — especially with the sterling reputation and praise Win7 is getting — but consider this one solved!

    Thanks for the Tip:)

    Were you trying to install it on a machine with a network domain user account that had Admin privileges? If so, then running as admin of the machine itself will always trump that in the case of installs. A Local Admin account always has more power. It was the same way with XP, it just wasn’t as strict. So, it’s not really an oddity but a solution by MS to address all those years of concern about the security holes that plagued ( and continue to do so) XP.

    That is correct Mark, but note; there are several instances where the installer does not run correctly in the GUI WIN7, particularly the 64bit version ( Ifound a few in Windows 2008 server as well). The work around is indeed using the shell. Remember also, there is a posibility Microsoft assumes Admins will or should used “power shell”
    If you remember Exchange 2005, most admin tasks had to be done using power shell. So I am assuming MS wants to harden the security but at the same times, gives us…should I say, a brain tickle?
    Thanks…good article.

  • It turns out this resolved the issue for our 32-bit players, but those using 64-bit Win7 are still looking for a definitive fix. Powershell FTW?

    It doesn’t resolve the issue. I followed above steps but I still have same issue.
