Studio 2011 Prof & Studio 2015 FL

Question

Is it possible to install a license of SDL Trados Studio 2011 Professional and a license of SDL Trados Studio 2015 FL Plus on the same pc? Is there any conflict? Thank you!

If you have two separate licenses it will work. 
 
If you have upgraded the 2011 FL to 2015 FL (plus) I think your 2011 license is no longer valid, you can only install two instances of 2015.
