I have installed SW EE V9 on my laptop.
Just in case you have limited memory on your PC/server....
I just noticed in my taskmanager that the toolset launcher is running in the back ground & using 30Mb of memory.
The SWToolset.exe also uses 8Mb of memory, with no tools running (V8 uses 7Mb).
So after a cold boot the SW toolset consumes 38Mb of memory without even running anything.
I kind of liked the V8 toolset which had shortcuts installed in my Start menu...
