Here is another issue I come across when playing with the Lab environment at home. Installing the Lync Server Components I received the following error
Prerequisite not satisfied: Message Queuing Server and Message Queuing Directory Service Integration must be installed before attempting to install this product. MSMQ must not be in workgroup operation mode
The prerequisite was installed on the host machine but still keep receiving the above error. The fix is to make a change within the registry to force MSMQ out of workgroup mode.
Open Regedt32 and drill down to the following path
You will now need to change the Key value for “Workgroup” from 1 to 0. Once complete close Regedt32 and restart the installation process, it should now be successful.
