Message from webpage: xmlLib Error / msxml3 & msxml6

Hi OCN,

I would like to start of by stating that I am by far not an expert on XML so please bare with me. I have been working on this issue since last week and feel I am not really getting anywhere.

At work some users are getting an xmlLib Error when trying to run a certain web based database. We used to get it when running Windows XP machines but was able to fix by replacing the later version of msxml3.dll with a newer version containing certain security functions we required. Now with all of the Windows 7 machines the issue has returned but the old fix obviously does not work. At first I thought it may have been because the dllcache folder is no longer called that in Windows 7, which is correct but changing paths to reflect the changes did not fix the issue. I am leaning towards msxml3.dll not being used in Windows 7 and that it must be a newer version, msxml6.dll?? The other reason I want to think this is because awhile back when I original was set to work on this issue, quit because more important things came up, I was reading in the code reference to msxml3.dll but nothing regarding newer versions of this dll. I have also been searching around the net via Google and have not came up with anything close enough to try. Again though I am not very good with XML at all so I may be talking gibberish. Please see below for the error message.


To me, even from my limited XML knowledge, the error appears to showing a invalid connection path to the database.

Any help would be greatly appreciated.

Thank You
Newb

Also if any other information is required for troubleshooting please let me know. Does anyone think running a validation on the code could be helpful? I did not write the code nor helped with it so I cannot say if it was done or not.

Well if anyone is interested I found this pertaining to my situation:


I believe this is basically stating you can't have two Document Type Definitions at once. When called XML DTD it is referring to an external DTD note to help define the structure of the XML document. When this is added into the XML document it is called XML Schema. I can't be for sure until the XML document is debugged but I believe this is the issue. I don't have access to the code unfortunately so I have to work through others to get this corrected.
