I have a development computer with Windows 8 and Visual Studio 2012, and I was planning on doing some tests with MSMQ. Everybody will tell you that you should just (in Visual Studio) open the references tab and add a COM reference to Microsoft Message Queue, but (yes there is always a but) the component was not present.
I looked for it in C:\Windows\System32 and C:\Windows\SysWOW64 and nothing there was nothing called mq*.tlb. So I found this thread in StackOverflow and it was pretty obvious :| I just had to go to Add Programs \ Turn on Windows Features and select it:
Figure 1. Adding MSMQ COM components
And after that I could find a file called C:\Windows\System32\mqoa30.tlb and added that reference.
I faced this problem recently. I tried and tried but I got different error messages for uninstall Silverlight 4 SDK and I needed to upgrade to Silverlight 5.
So after a lot of tears and suffering I came across the Microsoft Fix it.
I runned this program and indicated that I wanted to uninstall Microsoft Silverlight 4 SDK and it was like magic!
It checked the registry, and fixed it, and then uninstalled the MS Silvelight 4 SDK.
After that I just download the new installer run it and everything work! Isn’t it something J
