“Error 1327 Invalid drive” when installing Office 2003

Problem

When installing Microsoft Office from your hard drive you get the following message:
“Error 1327 invalid drive D:\”

The drive letter may be different from what is stated above.

Solution

  1. Click the Start button. (Windows XP users should then click Run)
  2. Type regedit and press Enter.
  3. In the Registry Editor go to: HKEY_LOCAL_MACHINE ->Software -> Microsoft -> Office -> 11.0 -> Delivery
  4. Located in this folder there will be 1 or more subfolders, click on each subfolder and look for LocalCacheDrive.
  5. Right click on LocalCacheDrive and click Modify.
  6. Change the D (or whatever letter appears in the error) to the letter of the drive you are installing from (e.g. C).
  7. Close the Registry Editor and try installing Office again.

Now when installing, it may say that it can’t find a “.cab” file. If that happens:

  1. Click OK and it will bring up a box to search for the file.
  2. In the Path box, change the drive letter to the same letter as the drive you are installing from and click OK.

  1. Worked, with a slight modification

    This did not exist for me, HLM\software\Microsoft\office\11.0, but I searched for “localcachedrive” and found the same structure in a slightly different place. I modified it from F to C (I don’t have an F drive). Office patches went through on the retry without error.

    Thank you!

    1. Thanks, your suggestion was helpful! Im on Win 7 so that localcahedrive was in a completely diff location!

  2. I went to device manager> disk management and changed the CD ROM drive to the drive letter indicated by the error and it worked OK.
