Got error while updating butterfly

grasshopper butterfly

Thanks, Mostapha.

I followed your suggestion but it was not successful.

Then, I noticed that I have the following three folders in the script directory, so I deleted all three of them:

C:\Users\USER_NAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\butterfly
C:\Users\USER_NAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\butterfly_grasshopper
C:\Users\USER_NAME\AppData\Roaming\McNeel\Rhinoceros\5.0\scripts\butterfly-plus-master

  1. now the update is successful with no warning:

    Image 7
    Image 7907×289 28.5 KB

  2. However, the 3rd folder butterfly-plus-master is not installed:

I wonder

  1. how this butterfly-plus-master folder is installed previously?
  2. why the existence of this folder will affect the update?
  3. whether it is required to run butterfly?

Thanks.
