Dear Dr. Heimes,

 

I want first to thank you for that detailed report.

 

Our Windows installer uses the NSIS Inetc plugin:

http://nsis.sourceforge.net/Inetc_plug-in

 

That plugin is documented to use the Windows proxy settings (at least those configured for Internet Explorer).

 

Can you try again with CGAL-4.3-beta1-Setup.exe? In that last version of CGAL, I have fixed a bug in the installer that could be related to the error you got (File Open Error), but is not related to proxies: the error may be that the destination directories do not exist. Do you have the following empty directories in your distribution of CGAL-4.2?

auxiliary\taucs\include

auxiliary\taucs\lib

 

Is that bug specific to TAUCS/LAPACK, or does it occur also if you tic the GMP/MPFR checkbox?

 

 

Best regards,

 

Laurent Rineau
