Installation query (urgent)

Hey there! I am using windows 7 Ultimate and was trying to install liberoffice 6.0.4 version and am facing this notification each time i run it
if the above pic does not load it says - liberoffice6.0.4.2 cannot be installed on this windows version. windows7SP1 or newer is required.

Am i downloading the wrong version? If so which one should i download (it would be appreciated if u could attach a link)
see the whole reason I am downloadingLO is because i have to give a ppt tom and my school uses LO3 version. So can u plz tell me if a powerpoint ppt(transitions, fonts and all) works in that version of LO.

Please reply as soon as possible, Thanks!

LibreOffice 6.0 only can be installed on Windows 7 with service pack 1. If you do not install SP1, then you can use LibreOffice 5.4.

Both versions - 6.0 and 5.4 - may be downloaded from this page.

At the time of writing this answer, version 5.4 was indeed available on the linked main download page. Now that it’s long EOLed, it may be downloaded from Index of /libreoffice/old/

Yes, LO3 has Impress for presentations, and features include transitions and fonts. Download the highest version of LO3 from the archive at Index of /libreoffice/old/

If your school uses LO3, then it sounds like that version would be best for you as well, to ensure maximum compatibility, especially since you are limited to an older operating system.

Save as .odp rather than .ppt.

The error message sounds like you may not have installed Service Pack 1. That is probably something you should fix in order to minimize the risk of viruses. LO3 is also somewhat out of date in terms of security, so upgrading to a newer version would be ideal.
