When I try to install hgu133plus2.db in R studio, it automatically starts to install org.Hs.eg.db.

And then it tells me the error: dependency 'org.Hs.eg.db' is not available for package 'hgu133plus2.db'

I have no idea what to do... Thank you so much for helping me!

if(!requireNamespace("hgu133plus2.db",quietly = T))
  BiocManager::install("hgu133plus2.db")

FYI, you can just do

BiocManager::install("org.Hs.eg.db")

And you will for sure get the correct version, whereas downloading directly provides no guarantee of that.
