HELP: Opening OTT and Serum in FL Studio

I'm running windows FL Studio on mac and I'm having trouble with Serum and OTT. They show up in the plugin database but mess up when opened. The answer to Serum's problem is solved in this thread: https://www.xferrecords.com/forums/general/help-unable-to-load-serum but I wanted to know if it was the same problem with OTT. The link to the other thread provides a photo of the same problem I'm having with both Serum and OTT.

You need to use FL MacOS (native). FL Crossover is a (defunct) experiment and lacks proper VST support (as mentioned on their downloads page).
