The application is not compatible with 64-bit versions of Windows 7. You can download the 32-bit version and it will install without problems but the problem is the installer that's not compatible. The application might work but since there is a problem with the installer, you will never have the possibility to install it. My advice is to install the 32-bit version on your co-worker's computer and then manually copy the whole folder from Program Files and transfer it to your computer. Right click the executable file and select Properties > Compatibility > Windows XP and launch it afterwards. If it's not working, then the program is not compatible with Windows 7 64-bit at all.
