Windows cannot find regedit need HELP!

[KrayolaKat]

My computer has two separate drives: A 120GB SSD and a 1 TB HDD. Windows 8 is installed on the SSD and intend to use this drive (C: just to store the operating system). I want everything else stored of the HDD which is labeled as my D: drive. To avoid program files from being installed on my C: by default (Like Origin games, which does not ask you the location where you wish to install) I changed the default installation direction in the registration. Here is exactly what I did:

- run regedit
-accessed HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
-changed ProgramFilesDir PATH from C:\Program Files to D:\Program files, along with ProgramFilesDir (x86)
-Rebooted to allow changes to take affect

When the computer rebooted I tried to run regedit again and an error notification came up that says:

Windows cannot find C:\Windows\regedit.exe. Make sure you typed the name correctly, and then try again.

I'm assuming I made a mistake when entering the new path names but I can no longer view the registry to see if that is the case because no matter what I do I cannot get regedit to run. I have been looking around everywhere for a solution.

-tried running regedt32 or regedit32 or REGEDIT

- the regedit.exe does exist in the system. When I open C:\Windows I can see the regedit application

- I tried doing a system reset with Alt + F10 but it says the C: drive is not there.

- I can download things but not install them.

Please if you have any advise on how to fix this.
