According to the system requirements, the x64 version of Windows 7 is not supported in CS3 but as always, there is a work around!

1. Run cmd.exe with administrator privileges (Start > type ‘cmd’ then right click on cmd.exe and select Run as Administrator, then click Continue when prompted by the elevation consent dialogue box).  This will open a command prompt in c:\windows\system32
2. Type cd..\SysWOW64
3. Type regsvr32 jscript.dll
4. Type regsvr32 vbscript.dll

That should work; you can now run the installer.

The problem is that the Photoshop installer is a 32-bit program, which means that it needs access to all 32-bit DLL’s and COM registrations.  Strangely, the 64-bit DLLs on x64 Windows are in the \system32 directory and the 32-bit DLLs are in the \SysWOW64 directory.

WoW64 means ‘Windows on 64-bit Windows’ and it contains all the 32-bit binary files required for compatibility.

Let me know if this helps anybody.

The first thing to bear in mind is that Exchange 2007, the latest version of Exchange, will only be supported on 64-bit servers.  Initially this may sound like an odd decision by Microsoft but they claim that almost all new server hardware these days has 64-bit technology anyway which means that new installations will be able to utilise better sizing and scalability options.  If you refer to Microsoft’s documentation, it clearly states that in order to run Exchange 2007 you’ll need x64 architecture with either an Intel Extended Memory 64 Technology (Intel EM64T) processor or an AMD processor that support the AMD64 platform.  The Intel Itanium family IA64 processors are not supported.

You’ll also need a minimum of 1GB RAM although 2GB is recommended and at least 1.2GB of hard disc space, which must be formatted as NTFS.

To check if your processor is compatible, you can use CPU-Z which is available here.
