Is it possible to install LibreOffice without uninstalling Apache OpenOffice?

Is necessary to deinstall openoffice before installing libreoffice in windows 7?
Thank you.

Release Notes - LibreOffice 3.5.5 Final (2012-07-11)

For Windows users that have OpenOffice.org installed, we advise uninstalling that beforehand, because it registers the same file type associations.

But apart of file associations, you can have both installed without troubles, I have three LIbreOffice. plus OOo.
