I have used version 3.4 in Windows 7 and wanted to upgrade to the latest version. However, I’ve tried 3 times and the installation has failed. I keep getting the message that the process was interrupted, even tho I haven’t touched the computer. I don’t want to delete my previous version, as it has many, many documents I need. How can I successfully download without losing my previous documents?
Please have a look at Problem updating - #2 by ROSt53
Additional hint: When you upgrade from 3.x to 4.x I recommend to save first your user file.
In XP the userfile is stored in the …/Application Data/LibreOffice. In W7 it should be very similar or the same. Make sure you can see the Application Data folder; folder properties must be set accordingly.
An upgrade of LibO doesn’t touch your data (Writer, Calc, Impress etc files.)
