Phenotype says it requires an updated version to run. I have version 2.0.1 and I
m using the update program after uninstalling Synplant, but it will not update to 2.0.2 . Is there some other way I need to uninstall to update? Or is there a link I could get to the actual most updated version file?

I figured out the problem, basically. I had made a backup of the VST in the folder that REAPER scans, so it kept using the old version in the backup. I had to move the backups to folders that REAPER does not scan and then install Synplant 2.0.2 then it worked.
