OH， I am sorry for hearing about that. I was lucky because I unchecked that checkbox when I installed it. You'd better never let the installer to update your PATH. I created a local folder where I put all of my DLLs, and set it in the path, therefore, we can avoid swelling the PATH.

Hello,

I just encountered a problem with the installer of CGAL 4.2 on Windows 7 x64
concerning the windows environment variable PATH. CGAL Installer replaced PATH
by auxiliary\gmp\lib instead of adding the latter to PATH.

What I did:
I went through installer options and changed Install directory to a different
drive letter (F:\cgal-4.2) and allowed the installer to ADD gmp-lib path to
PATH.

What I noticed:
When setup was completed, some things on my system were very strange: I colud
no longer call some system programs from command line which had been possible
just minutes before. I checked my environment variables and found PATH was set
to:
PATH=F:\CGAL-4.2\auxiliary\gmp\lib

(please note that PATH had been several hundred characters just before,
include C:\Windows\system32 to start with.)

When I uninstalled CGAL, PATH was empty afterwards. It will take me some time
to fix my system... :-(

I'd appreciate if you could check and maybe fix the cgal 4.2 install script.

Best regards
  Manfred

P.S.: I found that the installer suggests to use the folder "C:\Program Files
\cgal-4.2" when I choose to install 32-bit libraries. The folder "C:\Program
Files" is meant to host 64-bit applications on x64 versions of windows.
Microsoft suggests the folder "C:\Program Files (x86)" to install 32-bit
applications on a Windows x64 system.
