Can i delete all the previous versions of LibreOffice?

I have LibreOffice version 4.4.2.2 in my Windows 7 Professional (sp1) HP computer today. Can I delete all the previous versions of LibreOffice from my computer? If I do, will it cause my present version to not work properly? Please explain in simple novice teams. From: cliffofeck@yahoo.com MAY THE BLESSINGS BE

No, you should be able to uninstall them without affecting the current version.

however, I have found issues with 4.4.2 repeatedly crashing and have reverted to 4.3
