Is there any chance to run File Express on Windows 7 64 Bit?
The software doesn't support Windows 7 64bit. I have tried on Windows 7 and Windows 8.1 and the result was the same: failed to run the installation file. You need to install Windows XP in a virtual machine to be able to run the application. You can use VirtualBOX for this purpose.

The main download file should have the 64bit version but if it dosint try running compatibility mode.
