Unable to access my Libre Office Documents

I recently updated my Libre Office program to the latest version from a older version and now my Libre Office documents won’t open and neither will Libre Office itself. My Norton Security updated it.
Anyone know why this is happening ?

Can you tell exactly what happens when you start LibreOffice? Like, do you get an error message, and if so, what does it say?

You say: “My Norton Security updated it.” What do you mean? That Norton updated LibreOffice? That sounds very suspicious to me.

Can you configure privileges or rights for LibreOffice in Norton? Because maybe it gets too few of them.

Norton informed me that Libre Office needed updated so I clicked on ‘Update’ and Norton updated it, after it was updated I could no longer access Libre Office. It won’t even start up.
My O.S. is Windows 10. Libre Office is now Version 7.3 which was updated from 6. something or other, sorry don’t know exactly which version the older one was.

Thing is, I can’t start Libre Office at all, it won’t start. My Bullguard security was recently changed over to Norton automatically. I assume that Bullguard was taken over by Norton.
As for configure privileges or rights for LibreOffice in Norton. I simply don’t know and wouldn’t know how to anyway. I backed up a lot of files to Norton Back-Up but can’t find how to access those backed up files.

Who says I run two antivirus programs ? I only have Norton. Also, what makes you think that Norton is blocking Libre Office ? I think it’s something to do with the update.

So if Norton has control, then what’s the point of Norton ? How do I get back control of Libre Office from Norton if that’s the case ?

Search in Norton help for Allowed list, the term white list is no longer used.

You need to add soffice.bin to the allowed list, although some anti virus can identify LibreOffice.

This FAQ might help, General Installation Issues (Windows) - The Document Foundation Wiki

Went into Norton Help but cannot see Allowed List anywhere.

Try Application blocking

[EDIT]
possibly this Allow applications to run | Norton Community

Can’t see ‘Application Blocking’ anywhere either. Where is it ? What I need to do I think is undo the Libre Office update and return to the older version but I can’t find a way to do that.

Ok, as you are the expert here:
There is no easy way to revert an update unless you made a safety backup before and could return there. But you can uninstall LibreOffice, then re-install the older version you like.
.
To uninstall I use the control-center, but there are several ways. Instructions by M$ available here:

To re-install a special version you may need either to find your last download or use the archve-section on LibreOffices download-page (there is a link at the words “in the archive”):
https://downloadarchive.documentfoundation.org/libreoffice/old/
.
If the other opinions here on anti-malware problems are right, this step may help (if there is an older allowance for the older version) or even be impossible (if all installs are blocked). But maybe you will get an error-message wich could help.

It seems your sys-admin has either no clue what he/she is doing or there are reasons to protect the system from being altered…

I tried installing the latest version but the installation could not be completed.

Sorry. I didn’t read the comments closely enough; Norton upgraded you from LibreOffice version 6. That means it could be an issue with graphics. LO 6 used OpenGL but it had a denylist for some graphics cards, LO 7 uses Skia and there might not yet be a denylist, or your card might not be on it.

  • Click *Start menu - programs - LibreOffice - LibreOffice (Safe Mode) *.
  • In the dialogue that opens click the option button * Configure - Disable hardware acceleration (OpenGL, OPenCL, Vulkan)*. Cliick Apply Changes and Restart.
  • If LibreOffice opens then
    • Click Tools - Options - LibreOffice - View
    • Untick Use Skia for all rendering
    • Click OK

Hopefully that solves the problem.

I downloaded and installed Libre Office 7.3 and everything now seems to be working fine. Thanks to all who tried to help. Much appreciated.

But, now you say that you downloaded and installed v7.3 and everything seems fine. I wonder what the difference was between the first action and the last. Norton again?
