I cannot remove or upgrade LO 5.3.3.2

Every time I try, including safe mode, I get this message. I don’t know where the folder is that I should be targeting with the browse button.

The feature you are trying to use is on a
network resource that is unavailable.

Click OK to try again, or enter an alternate path to the folder containing the installation package
‘LibreOffice_5.3.1_Winx64.msi’ in the box below.

It means that you have not installed the program properly. You should uninstall and reinstall again. To uninstall, you will need to download exactly same version (5.3.1.2) that was used for installation. Download it here. You may also consider installing a newer version (either from 5.3 branch, or from 5.4), which is also available there.

Thanks Mike
