it is possible to install both inventor pro and inventor suite on the same PC? (or create chortcuts to run installed inventor as pro or suite)
This is not possible.
If you use network licenses, you can install Inventor Pro on all the client machines.
In this way when you start Inventor, the application will take an Inventor Suite License if available on the server, otherwise, will cascade to the Inventor Professional one.
In case the application gets the Inventor Suite License from the server and the user try to use a Professional module (i.e.: he clicks on a Tube & Pipe command), Inventor dynamically will take the Professional license and return back to the license server the Suite one that will be available for other users.
After that, if you want to return back to the license server the Professional license and use the Suite one, you need to restart Inventor.
Instead, if you are using Stand-Alone licenses, you have to decide in advance on which machines you want to install Inventor Pro and on which machines you want to install Inventor Suite.
You can find more details on our blog at the page http://beinginventive.typepad.com/being-inventive/2011/05/installation-interoperability.html .
The post applies to R2011 as well.
