For information: usually when an OO file does not open with a double click, the computer has lost the File Association that tells it to use OO to open that type of file. By right clicking on a file of a given type, one normally gets a popup menu to say (words to the effect) "Open with" presenting a list of applications. From these one should select OpenOffice and find the option that says (words to the effect) "always open with this application". If OO is not offered as an application there may be a further link to "other applications", which allows one to navigate to and select OpenOffice.
For specific operating systems there may be shortcut methods of doing this for all OO-type files, rather than individually for each type of file.
Apache OpenOffice 4.1.9 on Xubuntu 20.04.1 (mostly 64 bit version) and very infrequently on Win2K/XP
