Cannot get 6.5 to run

[dhopki]

I used to have 7 running successfully on my PC but wish to now use a chart plugin that requires 6.5. I deleted 7 and downloaded and installed 6.5. However 6.5 will not run. I get the error message shown below.
I am running Win XP Pro SP3 build 2600.
I have tried uninstalling/reinstalling the download after clearing all Ninja files and cache.
I have the latest MDAC version 2.81 and Jet Version 4.0.9511. I have also tried the recommended repairs to these from this forum and various utilities which report they are in good shape.
I have tried renaming the db to force a new db on installation. Nothing has worked.
I would really appreciate any thoughts anyone might have on this situation.
I note that the error message shows a double backslash before 'db' and wonder if I can correct this path somewhere?
Thanks in advance, David
