I wanted to play around with Revit MEP and Revit Structure, so I :
- Set up a virtual PC,
- Installed Windows 7 64-bit, and then
- Installed the Revit software.
The virtualisation software that I used was VirtualBox, as this allows for 64-bit guest operating systems.
If you don't have a copy of Windows 7 64-bit handy, you can download the media from the internet. You can also reset the activation period to allow for 120 days use.
Please note that you will need some decent hardware to virtualise Revit in a 64-bit environment :-)
