RailsInstaller on Windows 7 64bit?

I tried to use the Rails Installer to get a ruby on rails environment on my Windows 7 64bit today and the .exe won't run because it's made for 32bit instead of 64bit.

Update When I try to start the installer, this message pops up:

Here is the trans开发者_运维百科lation:

This version of the file is not compatible with the running version of Windows. Open the system information of the computer to check if a x86 (32bit) or x64 (64bit) version of this application is neccessary and contact the software vendor.

Is there a 64bit alternative for the installer?

64bits Windows can run 32bits applications, that is what WOW64 layer provides (Windows on Windows)

However, there are specific things you can't perform, like accessing OLE or using 64bits DLLs from 32bits applications or viceversa.

If the issue you're having is connect to a MySQL installation (something you're not mentioning) you should take a look to this blog article:

Hope that helps.
