I am using a User account (supposedly with administrator privileges), and I suspected that could have something to do with it. I just tried to install under a "real" administrator account, and then it works. Only problem now is that I cannot invoke the "Create Quadpatch" icon, but it is in the Draw menu, so not a big deal.

Thanks a lot for your help!

Thanks for all the great work. I have a problem installing TT_Lib2 and Bezier Surface to my Sketchup 2013, actually on two different computers, one running W7 32-bit and one running W8 64-bit. The error messages are the same. I am told TT_Lib is not installed although it is listed under extensions, and then I get the following error messages in the Ruby Console:

Error Loading File C:/Program Files/SketchUp/SketchUp 2013/Plugins/TT_Lib2/core.rb
5: Access is denied. - C:/Users/Anybody/AppData/Local/Temp/TT_Lib2.rb/2.9.15/1.8/win32/tt_lib2.so

Do you have any idea what causes this? I have searched the net, but without success.

Hi all,

I struggle a bit with this plugin; after manipulating the control points and closing the group, I cannot see an "Update FFD" menu item. I believe an earlier poster had the same issue. Can anyone help? Thanks.
