Issues with installing MSBee as a non administrator user
MSBee requires administrative rights to be installed and same thing is true for .Net Framework 1.1 SDK as well. If you are running your Windows under a non adminstrator user, you can use MakeMeAdmin script to install both MSBee and SDK.
However as noted in the MSDN forum by Alan, after installing SDK the first time you start Visual Studio 2005, you must have admin rights as well for it to run correctly since it tries to register type libraries from the SDK. After it is launched with admin rights for once, you can continue using it as a restricted user.
