After performing update the existing LibreOffice general icon which is pinned to the taskbar is invalid and must be deleted. Then a new pin needs to be made from the refreshed program shortcuts.
Most native-Windows installations allow for programs to remain functioning as previously pinned to the taskbar, unless a directory change is performed during the update.
After re-installing/updating LibreOffice, the LO-specific icon is gone, and a generic white icon exists at the location of the pinned program. This needs to be removed by the user and the newly installed app re-pinned. (That's a lot of additional user-required steps)
I am also experiencing this problem. I just saw it with the installation of LibreOffice 184.108.40.206.
I am running Windows 8.1 and have LibreOffice Calc pinned to my taskbar since I use it almost daily. I also have a spreadsheet that I use regularly pinned on the jump list. Whenever I install a new version of LibreOffice, the Calc shortcut does not work, even though the path to Calc is still valid. So then I have to unpin Calc from my taskbar, repin it, and repin my spreadsheet to the jump list, which is annoying.
I suspect that the reason for this is because the MSI installer first uninstalls the old version, which includes removing LibreOffice shortcuts. Somehow this must mess up the shortcut on the taskbar.
