How to re install SR?

my Rhino 6 updated itself.

But now when I start it, it complains a lot.
like:
RDK plugin does not load.
RhinoCycles.rhp does not load.
3dxrhino.rhp does not load.
saying:
This plug-in is designed to run in the latest Rhino 6.0 Service Release

Rhino runs, but many things do not work

Checking for updates it announces that it is up-to-date.

How can I reinstall SR?

Hi Aki - In the Wndows Control Panel > Programs > Programs and Features, you can use the Change options and then click the Repair button.

Was not that easy.

These are the 5 warnings, and in this order.

Hi - can you check if these are loaded and enabled in the plug-in manager?

-wim

typing and executing command PluInManager performs something else

Also from toolbar icon Plug-In Manager

does perform that same command (ie Page to display (Render) etc…

Use ! _-OptionsPage _PlugIns - should do the same thing

The command PlugInManager is just an internal alias for the above, both work fine here.

Have you tried completely uninstalling and reinstalling Rhino?
You can download Rhino 6 SR18 from this link.

Not yet.

Silence had reasons. Starting to uninstall Rhino 6.18 brought up a Rhino 6.17 uninstaller.
Running it resulted blue screen and dead computer.
Took up to now to repair installation (probably corrupted ntoskrnl.exe).
