iTunes not installing, invalid drive?

Well here's another technical issue for ya. As per the screenshot - you try to install iTunes and it says "Invalid drive: E:\" or F: or what have you. Usually happens when you install iTunes onto a portable hard drive, or something like that.


How you cheat it is, again, with the Command Prompt. So:
  1. Start -> Run -> "cmd"
  2. "subst e: %TEMP%" (where "e:" is whatever drive is causing the problem)
  3. Try installing again
That should solve it.
The more technical reason is:
  • Somewhere in the registry, it's told to look at E: drive for iTunes stuff
  • E: normally doesn't exist (portable hard drive & all)
  • So it gives an error
  • "subst" says "pretend that e: is this directory (usually C:\Temp)"
  • Cheated!

Obviously, plugging in that portable hard drive and installing would be the easiest way to do it.

Now I think of it.

Bleh.

I stumbled across this and appreciate it a lot. But, it isn't working for me. I'm typing in your suggestion in the control panel. I am having the "E" drive error and I know it is because I installed iTunes on an H drive. It all stopped working last fall and I'm trying to repair it now. Any other thoughts o tips? Thank you.

Hi there,

Are you sure you're typing:

subst h: %TEMP%

into the Command Prompt?

It should work, but things might have changed in the last year.

Which version of Windows are you using?
