How do I initiate an earlier version of LibreOffice (4.3.2.2) if it’s stored in the archive?
What do you mean as “initiate”? Do you want to install an older version? Or do you want to adjust some settings in the installed older version?
I’ve never tried it before but it seems straightforward to download. Go to the archive page.
Click on the version number,
click on your operating system,
click on the version for your operating system x86 or x64,
click on the version for your language/locale to download and then also the appropriate help pack.
By initiate, do you mean install? You have to do that according to your operating system.
Following Mike Kaganski’s answer for question 303279 you should download the latest bugfix version 4.3.7.2 for OS 10.6 & 10.7
