Good Luck HTH.Is there a program that lets me install and run programs on an external hard drive?I believe there's no such thing. When you install application, no matter what it is, it's also installed in system partition (C:\Windows) so it's not only installed in the application's folder. So if you use the external HDD with different computer, how does the OS will understand the application in the external HDD since the information is saved in previous computer?Is there a program that lets me install and run programs on an external hard drive?If you have connected the HD up to any computer, and installed things onto it, they will be available for use off the HD, you don't need a program to run files on a portable HD. The HD will appear in My Computer when you connect it. Just click on the icon and it will open up your HD.Is there a program that lets me install and run programs on an external hard drive?try this.
