Hi all,

A little background....  A few of us running Win7 x64 carried out manual installs of Lync 2010 client.  Later, a few weeks down the line we deployed Lync to the rest of the organisation (all Win7 x86) using a GPO that pushed out the Lync MSI.  This worked fine and all the machines received it ok.

I am wondering if this GPO might have applied to our x64 machines and screwed something up?  Lync works fine, it's just that we can't install this update.

Running Windows 7 x64.  When I try to install I get:

The Installer has encountered an unexpected error installing this package.  This may indicate a problem with this package.  The error code is 2727.

In eventvwr I get:

Windows Installer reconfigured the product. Product Name: Microsoft Lync 2010. Product Version: 4.0.7577.4356. Product Language: 1033. Manufacturer: Microsoft Corporation. Reconfiguration success or error status: 1603.

Log file show:

The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2727. The arguments are: INSTALLDIRECTORY64, ,

I used msiexec to create a verbose log file and the bold part stands out:

I am now also unable to reinstall or uninstall Lync 2010. :(  Any ideas?
