[LLVMdev] LLVM 3.4 RC3 fails to run on Win32

Hello Peter, hello all,

Maybe. To be more concrete, here are my observations with more details:


My test system:
Microsoft Windows XP
Professional
Version 2002
Service Pack 2

Intel Atom N450
with physical address extension (PAE)

As far as I remember there were no updates to the operating system.


The installation of LLVM-3.4-rc3-win32.exe worked flawlessly and only 
sported the following message in a command line window:
===>
Installing MSVC integration...
Failed to find MSBuild toolsets directory.
MSVC integration install failed.
Drücken Sie eine beliebige Taste . . .
<===
This was to be expected since no MS C compiler is present.
The last line means "Press any key to continue".


The MS common runtime library DLLS are as follows in C:\windows\system32\  :
msvcrt.dll: 7.0.2600.2180 (xpsp_sp2_rtm.040803-2158)
msvcrt20.dll: 2.12.000
msvcrt40.dll: 5.1.2600.2180 (xpsp_sp2_rtm.040803-2158)
msvcr70.dll: 7.00.9466.0
msvcr100.dll: 10.00.40219.1
msvcp50.dll: 5.00.7051
msvcp60.dll: 6.02.3104.0
msvcp100.dll: 10.00.40219.1


All programs of LLVM\bin\ fail by popping up a window with the following 
message:
===>
C:\Programme\LLVM\bin\clang.exe ist keine zulässige Win32-Anwendung.
<===
This means "... is not a valid Win32 application".
