For the Lync tests not working concerns. We have a pre-req for the Unified Communications Managed API 4.0 (UCMA) DLLs for the Lync test to work properly. We aren't able to ship them with the product at this time. To install the DLLs - go here - http://www.microsoft.com/download/details.aspx?id=34992. We will work on improving the pre-req check/handling in a future release.
For the installation issues, we need to work directly with each of you to see the exception error details. Please send us email to mcafeedback@microsoft.com with as many details as you can share about what is breaking and we'll do our best to troubleshoot those issues and get things working.
As always, feel free to send direct feedback to mcafeedback@microsoft.com.
Thanks.
The MCA Team
