Setup Office2003 "Invalid Drive" message (solved)

[ChrisGreaves]

I inserted the CD and used Setup.exe and after the splash screen received the message
"Invalid Drive I:"
(quantities may vary)

1. Using the DOS command SUBST to fake a drive I: didn't solve the problem
2. A Google Search got lots of hits.
3. From the First hit the suggestion "Before you try to install Office 2003, check to see if the MSOCache folder exists" led me to find a folder C:\MSOCache, but it was apparently not usable by Setup.exe. (It did contain a subfolder "Users" etc.)
4.From the same page the suggestion "the location that is specified by the LocalCacheDrive registry subkey" led me to search the registry for the key "LocalCacheDrive".
5. I found the first instance at

Code: Select all

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\11.0\Delivery\{91110409-6000-11D3-8CFE-0150048383C9}] 
"CDCache"="2"
"DownloadCode"="90000409-6000-11D3-8CFE-0150048383C9"
"LocalCacheDrive"="I"

and changed the "LocalCacheDrive"="I" to read "LocalCacheDrive"="C"
6. I did not change any other keys.
7. Following this Setup.exe ran without further problems. (But a repair did NOT fix the original problem, so I shall now un-install Office2003, reboot, and re-install).
