I cannot open the default rhino5 toolbar “.rui” anymore even after 2 reinstall?
Any idea

Commande: _Toolbar
Erreur de lecture du fichier “C:\Users\Steven\AppData\Roaming\McNeel\Rhinoceros\5.0\UI\default.rui”
’.’, valeur hexadécimale 0x00, est un caractère non valide. Ligne 111620, position 62.

Does the folder C:\Users\Steven\AppData\Roaming\McNeel\Rhinoceros\5.0\UI exist? Does it have a default.rui file in it?

If so, the file may be corrupted. You can first try typing the command _ToolbarReset in Rhino, follow the procedure and see if that fixes it.

If not, in the same folder with default.rui, there should be a file called default.rui.rui_bak. With Rhino closed, remove the corrupted default.rui , make a copy of default.rui.rui_bak in the same folder and rename it to default.rui. Then restart Rhino.

If neither of those helps, I don’t know what’s gone wrong…


Another thing to try is

Thanks Mitch, first step works fine!
