Question: Win7 and Compiler

I installed M16 32 Bit on my new machine with Win7 64 Bit.

But the following results in crushing mserver.exe:

  tmp := proc( x :: float ) :: float; 2.3 * x end proc:
  cp:=Compiler:-Compile(tmp);

with system info below. 

Do I have to set certain rights for the compiler or define a specific working directory?

The FAQ http://www.maplesoft.com/support/faqs/results.aspx?search=compiler does not help me.

Dito http://www.maplesoft.com/support/faqs/detail.aspx?sid=32630 does not help me much:
I have installed MSVC 2005 (=32 Bit), but want to use the Watcom compiler - as I did
before (and IIRC I was not asked during installation).

TIA,
Axel
