How to fix a new Scilab 5.3.0 install - failed 'converting libraries'?

[ray joseph]

I just attempted to run the newly installed 5.3.0 on a Windows XP laptop.
How do I fix the associated error (below):

Startup execution:
  loading initial environment

Start LCC-Win Compiler support
        Load macros
        Load help
Converting Libraries.
Build blasplus.lib
   'C:\Program' is not recognized as an internal or external command,
   operable program or batch file.
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.
Conversion failed blasplus.lib
Build lapack.lib
   'C:\Program' is not recognized as an internal or external command,
   operable program or batch file.
