Error "The system cannot find the path specified" When I try to install virtual reality (vrinstall)?

1 view (last 30 days)
I tried to install virtual reality builder but I get the error "'C:\Program' is not recognized as an internal or external command, operable program or batch file. " . I thought it might be because of the space in installed directory name "program files". so I remove and install the MATLAB again in the folder "programfile" (with no space in name). Now I get the error "The system cannot find the path specified. " . I am desperate and need to install it ASAP. Can anybody help?

Exactly what command are you using to do the installation, and is it at the MATLAB level or at the Windows level?
If you are currently calling vrinstall within MATLAB, using a command such as
vrinstall C:\Program And Documents\Asadi
then change the call to
vrinstall('C:\Program And Documents\Asadi')
in which you supply () around the path and enclose the path in apostrophes.

Well, in the command line I just type "vrinstal", then it says that"External VRML viewer is not installed. Install it? (y/n) " then I type y, then"
Installing blaxxun Contact viewer ...
Do you want to use OpenGL or Direct3D acceleration? (o/d) "
I type "d" but then "Starting viewer installation ...
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
External VRML viewer: not installed
VRML editor: not installed (will be installed on first edit)"
I even tried to use your advice which is
" vrinstall('D:\Program Files\MATLAB\R2010a\toolbox\sl3d\vrealm\program')"
I also tried
" vrinstall('D:\Program Files\MATLAB\')"
But i just get the error
??? Error using ==> vrinstall at 239
Invalid action name
What Should I do?
