Installing Rhino 5

Question: Why do I have two Desktop Shortcuts for Rhino V5?
Answer: Rhino 5 automatically installs both 32 bit 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 is 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 V5 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.

In order 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 bit and 64 bit versions of Rhino 5 installed on the same computer?”
Answer: Yes, no problem, except for the license manager issue as above.
