Installing back to 1.0.0

I’ve been working in Dynamo 1.1.0 but have been running into issues with plugins and wanted to install 1.0.0 as an option. I installed the 1.0.0 version, but when I open revit, my only options are 0.9.2 or 1.1.0 where is 1.0.0?

@Dennis_Goff - You will need to uninstall Dynamo Core 1.1.0 first before trying to install Dynamo 1.0.0 again. You will be unable to have these installed side-by-side. Please make sure you close all running Dynamo instances before uninstall/install. Having running instances may cause unexpected errors or corrupted files.
