I installed QGIS 3.16.9 on my Windows 7 64bit system and all the processing tools are missing (I noticed it when checking the vector menu). I have Python 3.8.10 installed on my system and I believe I have deleted all the data from a previous (and much older) QGIS instalation.
When I try to activate the processing plugin I cannot find it on the "Plugin" menu.
Does anyone know what the problem might be?
