Yippee, I think the message is really gone. I found this post:
"Close all open programs. Then in the registry editor, once you get to the folder listed above, right click on "Cache", left click on "Modify", paste in "%USERPROFILE%\Local Settings\Temporary Internet Files" (without the quotes), left click "Ok" close the registry editor. Restart the PC."
I have thought I had the right settings and I had tried changing and/or retyping the last part to say "Temprorary Internet File" or "Temp" but I didn't ever try copy and paste of the whole string %USERPROFILE%\Local Settings\Temporary Internet Files into the value for the "cache" and that worked. But what I also discovered what that there are two similiar folders, USER Shell Folders and Shell Folders
The value for both look to be similar. I think I had been adjusting and changing and modifying "Shell Folders" but NOT "USER Shell Folders". This time I copied and pasted into "USER Shell Folder". That appears to have made the difference.
HKEY_CURRENT_USER
Software
Microsoft
Windows
Current Version
Explorer
Shell Folders - Cache = Users\"me"\AppData\Local\Microsoft\Windows\Temporary Internet Files
USER Shell Folders - Cache = %USERPROFILE%\Local Settings\Temporary Internet Files
I am hoping all settings are now correct and all I can assume is that I was confusing one for the other, but at this point I can't be sure nor do I know what was the cause of the problem in the first place. I am just happy the error is now gone.
