MATLAB: Do I get warnings when I install V-Realm Editor in MATLAB 7.10 (R2010a) on a Windows 7 machine

Simulink 3D Animation

I install V-Realm using the following command at the MATLAB command prompt on a Windows 7 machine.

vrinstall -install editor

I get the following warning message on executing the above command

 Warning:  Cannot create V-Realm Builder preferences file.   Object libraries may not be available.
 >In vrinstall at 190

This also limits access of 3-D Objects Library in V-Realm Builder 2.0 to only those in the “General Purpose” category. I am wondering how can I get access to all of the 3-D objects built into V-Realm Builder’s Objects Library.

On Windows 7 installing any software requires administrative privileges.

In order to install V-Realm Builder through MATLAB please follow these steps

1. Start MATLAB with administrator privileges. To do this right click on MATLAB icon and select 'Run as Administrator'

2. Execute the following command at the MATLAB command prompt

vrinstall -install editor

3. Restart MATLAB

This message is printed when you are trying to install V-Realm Builder (an external VRML editor) on a platform that is not supported. V-Realm Builder is supported only on Windows.

For other platforms, please just use the built-in editor. This editor does not need to be installed, please just launch it by

edit(vrworld('your_vrml_file.wrl'))

or interactively from a vrfigure menu bar, or from the Apps bar. The built-in editor also works on Windows and may be a good choice over V-Realm Builder anyway.

================ NOTE: V-Realm Builder is only available for Windows ================

This error can occur if the vrbuild2.ini file is corrupted. The vrbuild2.ini file can get corrupted due to operations like system updates or running V-Realm independently of MATLAB.

The workaround is to replace the corrupted or empty .ini file (which is a configuration settings file) by executing the following line from MATLAB command window:

>> vrinstall -install

as per the latest installation instructions:

https://www.mathworks.com/help/sl3d/install-v-realm-editor.html

You can check your installation status at the MATLAB command window:

>> vrinstall -check

Further troubleshooting steps can be found in the V-Realm manual (execute from the MATLAB command window):

>> web(fullfile(matlabroot, 'toolbox', 'sl3d', 'vrealm', 'manual', 'vrealm_man.html'))

If you have custom libraries and wish to upgrade MATLAB release, you will want to save the contents of the following folder outside the MATLAB path before upgrading releases:

<matlabroot>\toolbox\sl3d\vrealm

These contents can then be copied over to the new "vrealm" folder at the same directory in the newer version of MATLAB.
