[pluggo] Installing Pluggo 3.6 to be used with max 4.6.2 having Max 4.5 on Computer

Can I install Pluggo latest version on my computer which is running max the latest (4.6.3) and also max 4.5 (that i need to use with old patches)? 

if i do it that means that i damage max 4.5 or that i just cannot play pluggo plugins with max 4.5?

or does it create conflicts?

thanx in advance
