This week (just so others can understand) I installed some of my older builds from 2011 into my game. (Houses) I used the Clean Installer to install them and it only ask me a few questions about any walls, tiles or objects in those houses. Like such and such is already installed did I want to go ahead and install the content from the house. I said no, of course, well I ran the program to check if it kept the duplicates out..no.
I had three or four copies of Almost Jade flooring from TS1 (which was a tile in one house) a few copies of objects I told it not to reinstall etc.
If it's my own lots I have packaged to file then decided to reinstall so I can put them in a new custom hood, the Clean Installer is hit and miss and may install any cc in that lot even if I said No. As I said, I wish someone could fix this. I have so much cc I don't really have time to run the clean installer daily to delete duplicates I told it not to do/install.
It seems it can't catch duplicates or even if you say No, it adds them anyway if it's one of your own packaged lots more often than not.
ETA: This may also happen because let's say I install a packaged lot (my own) and one says (older) Season's Version, or AL version in the description..then the Installer may not be able to see that stuff/cc is already in downloads since it's not the M&G version etc. Just a theory.
ETA: Clarity, if you select lot file you see which EP you had when you built the lot. Like up to Seasons it will say Seasons. So, if you install that lot and any cc in that file the CI may not catch any or just a few, but still install them though you said no.
