well, errr.
I solved myself.
I simply went into the plugins folder of sketchup and deleted the LibFredo folder along with the rb file and and copied back again. And now is working.
Thanks in any case

Hi.
Thanks in advance for any answer.
I have downloaded and install some plugins, i.e: LibFredo6, round corners and some others.
I own a Mac. I have Windows 7 running in bootcamp. So I use sketchup in both systems.
When updating the plugins in iOS it goes with no problem. But when I try to do the same in Windows it doesn't do it. although it use to do it previously.
Even Windows and iOS are running in the same machine they have their own partition and therefore installations of sketchup and plugins are totally independent one from the other.
Any help please???
