A few occasional problems experienced with installations and repair instructions

PROBLEM:

Missing toolbars and no plug-ins loaded on Vista

A small number of users have reported that installing Rhino V4 (SR2 and newer) on Vista has resulted in no plug-ins and no toolbars loaded unless logged in and running as the Administrator. This has been more common on Vista Home Premium systems, but has been reported on all flavors of Vista. Most users do not report this problem and we have not been able to duplicate the problem here in the Rhino Development Team.

SOLUTION:

Users have reported that if they turn off User Account Control (Control Panel - User Accounts), and temporarily disable any antivirus and system protection software before running the Rhino installation again, solves the problem. After reinstalling and running Rhino once, you should restart your antivirus and system protection tools. You can turn UAC back on if you want to as well.

Close Rhino 3.0

Run this utility: http://en.wiki.mcneel.com/content/upload/files/Rhino3_Registry_Repair.zip while Rhino is closed.

Restart Rhino

The utility can delete the following key in the registry to make Rhino “forget” some settings that make the toolbars not dock correctly.

HKEY_CURRENT_USER\Software\McNeel\Rhinoceros\3.0\Scheme: Default\Control bar manager

- to be used after upgrading cards and drivers

Close Rhino 3.0

Run this utility: http://en.wiki.mcneel.com/content/upload/files/Rhino3_Registry_Repair.zip while Rhino is closed.

Restart Rhino

The utility can delete the following key in the registry to make Rhino “forget” old OpenGL display settings

HKEY_CURRENT_USER\Software\McNeel\Rhinoceros\3.0\Scheme: Default\Options\OpenGL

PROBLEM:

When I try to install Rhino 4.0, I get a Windows Installer message saying the product must be uninstalled first using Add/Remove Programs, and it won't proceed with the install.

But when I try to uninstall with Add/Remove Programs, that doesn't work either.

SOLUTION:

This solution defeats the Windows Installer's safeguards, so use this solution only when you will install the product again immediately.

Use REGEDIT.EXE to remove this registry key (careful!):

HKEY_CLASSES_ROOT\Installer\Products\DFFBC2C5B3CF9AA499B3ECB2D82AB578

PROBLEM:

The Index tab of the Rhino Help or BonusToolsHelp window is blank

for low-privilege user logins in Windows 2000.

SOLUTION:

This is a permissions problem that interacts with a bug in Windows 2000.

Here's how to fix it without changing the permissions on Program Files folders.

Just have an administrator delete the file Rhino.GID in the …Program Files\Rhino\English\Help folder, and while you are at it, delete the RhinoBonusTools.GID

Then have the administrator log out (don't run the Help yet, or it will recreate the GID file for the administrator).

Have the low-privilege user log in. The Index tab should now populate (and a GID file is created somewhere in the user's personal files area.)

This trick is not needed on Windows XP, Microsoft fixed the bug.

Another way it can be fixed on Windows 2000

is to add the permission “Write” for Users on the …Rhino\English\Help folder
