Question: Why do I have two Desktop Shortcuts for Rhino V5?
Answer: Rhino 5 automatically installs both 32- and 64-bit versions and there is one shortcut for each. See this page for more explanations on why this is done.
Question: Why is the V5 installer refusing my old V3 or V2 key code?
Answer: You have a very old (SR0) install disc. There is a bug in the installer. The best thing is to download and run the latest installer package from here.
If that is not possible, turn on your keyboard CAPS lock when entering your old V3 or V2 key code and it will work.
Question: Can I install or uninstall Rhino 5 and keep my Rhino 4 install intact?
Answer: Yes, but with one important condition. Read on.
Rhino 5 is a completely separate installation from V4. However, it uses the same license manager as V4. Problems can arise if you decide to uninstall Rhino 5. The V4 license manager gets uninstalled in the process, and your V4 installation will stop working.
To prevent this from happening, if you decide to uninstall V5 , first copy the files McNeelLM.exe and RhinoLM.exe to a safe location, then uninstall Rhino 5, and then copy them back to the original location.
In Windows Vista or 7 the license manager is located at:
C:\Program Files (x86)\Common Files\McNeel Shared\License Manager (64-bit)
C:\Program Files\Common Files\McNeel Shared\License Manager (32-bit)
*You also want to be very careful with plug-ins, toolbars, etc. that might be shared between V4 and V5 - either consciously or inadvertently. This has been known to cause problems.
Question: Can I have both the 32- and 64-bit versions of Rhino 5 installed on the same computer?
Answer: Yes, no problem, except for the license manager issue as above.
Question: When I try to open a file, I get an error message about something being unreadable.
Answer: Here's how the system works. There are two parts:
Question: When I installed Rhino, I checked the option to use the Zoo, but I don't use the Zoo.
Answer: On Windows Vista or Windows 7, delete all the files in: C:\ProgramData\McNeel\Rhinoceros\5.0\License Manager\Licenses.
On Windows XP delete all the files in: C:\Documents and Settings\All Users\Application Data\McNeel\Rhinoceros\5.0\License Manager\Licenses
Note: On some systems, instead of the “\All Users\” folder, the path may be your “\Domain\” log-in name.
Question: I tried to uninstall Rhino 4.0, but an error occurred and Rhino could not be removed.
Answer: Manually remove Rhino 4.0.
Question: I tried to uninstall Rhino 5, but an error occurred and Rhino could not be removed.
Answer: Manually remove Rhino 5.
Question: What previous version info do I need to install my Rhino 5 Upgrade?
Answer: The Rhino 5 Upgrade installer will install if one of the following is true:
There is no need to install the previous version. Just have the key codes ready.
Question: I've got a new computer and I want to install Rhino version X SR Y. I have always purchased the upgrade versions of Rhino. Do I have to install all the previous versions and successive service releases??
Answer: No. Simply install the last upgrade version you have downloaded or from the DVD (download is recommended). During the install, you will be asked to type in a license key of a previous version to validate that you have it, but it is not necessary to actually install the previous versions. If you have installed from a DVD, use Help > Check for updates to see if you have the latest Service Release, if not, download and install that. It is not necessary to install any previous Service Releases.
Question: What are Service Releases?
Answer: These installers are downloadable and will only install if you have a version of the product already installed. Service Releases are identified two ways: the SR number, like SR3 or SR4b; and the date, which is coded into the name of the download file like 20050729, meaning July 29, 2005.
Question: How do I tell what version is installed?
Answer: Once you have the software installed, you can see the date and the SR number by viewing the about information, which appears on the splash screen when you start Rhino, or can be viewed by doing Rhino > Help > About Rhinoceros.
For Flamingo, do the FlamingoAbout command. For Bongo, do the BongoAbout command.
Question: Can I delete older versions in “Add or Remove Programs” without causing problems?
Answer: The Add or Remove Programs entry in the Control Panel in Windows is reporting all Service Releases as an installed program, each using approx. 250MB of disk space. This is somewhat misleading. Windows reports the total as though all installed files are added on to the existing installation even though many, if not all, files are actually overwritten on install. Do not use the Add or Remove Programs to remove older Service Releases of Rhino 4.0.
Question: How do I transfer personalized settings from one Rhino installation to another?
Answer: See this page with some advice on copying/transferring customized settings.
