Tried installing libre for windows, but it says install packet could not be opened, verify with vendor that it is the windows installer

Running a Samsung NC-10
Windows XP Home Ver. 2002 service pack 3

From where did you download? What did you download (=filename)?

From the Libre website and the file name was LibreOffice_4.2.4_Win_x86.msi
I’m just now realizing this is not an .exe file. I’m not familiar with .msi files

Have you tried to download it again?

Hello, I’ve tried several times deleting the previous download and I’m still receiving the Microsoft Installer fails to install…verify with vendor. I’m using Windows 10 platform, on an assembled system. Lots of storage and speed. LibreOffice 7

Your Download could be corrupt. Please try discarding your suspect download & try downloading again.

.msi files of LO have installed correctly for me in Windows.
