Hello to All.
I’m new to PC’s and haven’t used Rhino3d since the 90’s and was hoping to get help installing the Grasshopper Gold plugin. I’m hoping it’s still free.
Hi @Michael35
Welcome back 
Start by installing Rhino if you haven’t already. Then head over to Food4Rhino, register and download Grasshopper Gold. For help on installing, take a look at the FAQ.
HTH, Jakob
Hello Jakob.
Thank you for taking the time to help me. I keep getting an Error 0x80004005: Unspecified error code. I looked up the error code but PC’s are new to me and I lost.
Hi @Michael35
That’s a Windows error for when something goes wrong with reading the file off the disk. Things to check:
I’d start just re-downloading the file, to make sure it’s not corrupted.
If the file on a shared drive, try moving it to a local drive.
If it’s already in a folder on a local drive, try moving it to the Desktop.
Temporarily disable your anti-virus software.
Make sure that the file is not blocked
Also, run SystemInfo in Rhino and post the result here.
HTH, Jakob
