Downgrading from 10.5 to 10.4.1

[nicholasduncan2]

I am downgrading from version 10.5 to version 10.4.1 to use a specific set of tools and addins for the Range Managers Tool Kit but already authorized version 10.5. I have since uninstalled version 10.5 and installed version 10.4.1 and installed all of the tools but i cannot get ArcGIS Administrator to validate the 10.4.1 vice the 10.5. I have gone back through and conducted all of the steps and it says that it is good for 10.1 through 10.5 but cannot start ArcMAP due to it saying "Arc Desktop Basic is not authorized for use"

Thanks

I figured out a work around. I had to remove some of the addins then de-authorize the previously established 10.5 install through ArcGIS Administrator. After the de-authorization, pushed up the authorization again and it went through and re-populated in the registration details for use. Hope this helps anyone else that may have issues in the future.
