Download psexec from Microsoft TechNet and extract the contents to your desktop.

Open a Windows command shell

Change directories to your desktop.

In the command shell , type: psexec -i -d- sc: \ windows \ regedit.exe Thus, Windows will run the registry editor with the permissions of the System account ( more powerful than the Administrator account ) .

Go to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Installer \ UserData \

Click the right mouse button in the UserData folder and select Permissions ...

In UserData permissions dialog box , click Advanced

Make sure " Administrators" have permissions to "Full Control" and in this folder "Users" have permissions to "Read" . There are other user permissions, but Administrators and Users are most important .

Select the Replace all child object permissions for inheritable permissions from this object

Click OK twice to apply the permissions

Rhino install again.
