I have 3 internal drives on my laptop, C, D and F. My F drive died, which is where photoshop was. I changed my prefrences to D and tried to install, but I keep getting error 176 trying to install to a network drive. But it is not a network drive. I tried several times, then changed my preference to C but same thing. Always get error 176 at 8 seconds of the install. Have restarted the computer and tried again, same thing. What now?
Given what you said, I think it's still installed to F, even though it isn't there. That is, Windows knows where it is, and running the installer tries to modify it. See if you can add a USB key on F, to get over that, and uninstall it.
