 Grasshopper-Tekla Live Link installation
==========================================

1. Close down Rhino and Grasshopper.

2. Extract GrasshopperTeklaLink.[TeklaVersion].dll, GrasshopperTeklaLink.Loader.gha and GrasshopperTeklaLink.Setup.exe into any location on the disk.

3. Run GrasshopperTeklaLink.Setup.exe and allow admin rights if asked for.
   - This will unblock the files and place them in the Grasshopper Libraries folder, replacing any old link version there.

4. If using Rhino 8, launch Rhino and type the command 'SetDotNetRuntime' and select 'NETFramework', then restart Rhino.
   - This needs to be done only once.

5. Restart Rhino and Grasshopper if you haven't already - have a model open in Tekla first.


---------------------
 Manual installation 
=====================

Copy GrasshopperTeklaLink.Launcher.gha and GrasshopperTeklaLink.[TeklaVersion].dll directly into the Grasshopper Libraries folder.

    a. Open the Grasshopper Libraries folder 
         - The folder can be opened from within Grasshopper in the File menu > Special Folders > Components Folder.
         - The path will look e.g. like this: C:\Users\[username]\AppData\Roaming\Grasshopper\Libraries

    b. Extract GrasshopperTeklaLink.[TeklaVersion].dll and GrasshopperTeklaLink.Loader.gha into the Libraries folder, replacing any existing files.
         - These files can also be put into any other location that Grasshopper loads plugins from.
         - There can be multiple GrasshopperTeklaLink.[TeklaVersion].dll files in the folder for different Tekla versions.
           Grasshopper will ask which one to use at startup.

    c. Unblock the files if needed:
         - For both extracted files, right-click the file and select Properties.
         - Under the General tab, click on the Unblock button, and click OK.
         - If you don’t see an Unblock button, the file is not blocked.

    d. Remove any existing file named GrasshopperTeklaLink.gha or GrasshopperTeklaLink.gtlink from the Grasshopper Libraries folder.
