Access is denied (Exception from HRESULT: 0x80070005) with VMRCplus 1.8.0

I received several posts last week related to the error above. I am still investigating how/why this happened but it is caused by the fact that the .Net Framework 3.0 is missing from the machine where VMRCplus is being used. So to fix this for now, install the .Net Framework 3.0 (with SP1).
