Last chance for Open Office here

Downloading the latest version of Open Office here. Have been trying it out over the last year and I am underwhelmed. The amount of functions are fine, the interoperability with other formats are also "OK" for my use. But the fact that the different applications crashes on a regular basis is not! That is one thing I just can't work around. I can't trust a software that after an upgrade no longer can open documents created by the earlier version. Instead the application crashes every time I try and open certain documents...
As I write this I am downloading the latest version of Open Office and will give it a last chance to excel. (No pun intended! ;o)
If this version doesn't work better I have to go back to the commercial alternative. Unfortunately...

Update: The latest version of Open Office can't even go through the installation process here on my computer. It claims to have insufficient privileges to access the install directory. That is the same installation directory the very same installation program just created by itself...
Had to reinstall the previous version (to repair the damage), then uninstall it completely. THEN after that I could install the latest version. Not a very clear upgrade path if you ask me.
