Hi There,
I hate using 32bit software on 64bit OS. We use Office Communicator Server 2007 R2 at work and I wanted to use the new Lync 2010 client 64bit. So I installed and opened up Lync and it would fail with the following error:
“Cannot sign in to Lync.
Cannot sign in because the server version is incompatable with Microsoft Lync 2012. Connect your support team with this information”
To bypass the check, you do the following:
- Open up Registry Editor on your computer
- Browse to HKEY_CURRENT_USER\Software\Policies\Microsoft
- Create a new key called Communicator
- Create a new DWORD called DisableServerCheck and set the value to 1 (00000001)
Close out of Registry Editor and re-open Lync and you will find that it now opens and works.
There will some features that will not work and that is expected until to upgrade Office Communicator Server 2007 R2 to Lync 2010 Server.
Hope this helps someone…
Cheers
Stewy
