After installing SP2 for Win XP, I discovered that I need to have Visual
Studio 6 installed on my machine (in addition to VS 2003) so I can work with
some legacy VB6 code.

When I tried to install VS 6.0, I received the following error:
"msdasql.dll was unable to register itself in the system registry"

I tried unitstalling VS 2003, but this didn't help. I have tried installing
on a couple of different partitions, none of which contain the OS, to no
avail. I tried installing a new MDAC as suggested in article 259064, but all
MDAC components are now included in the OS so this didn't do anything.

Does anybody have any advice?

Try booting into safe mode and then installing the product. You may need
to go out and locate and rename the file.

I did try safe mode (at least safe mode w/network) this morning and it didn't
help. I'm a little nerveous about renaming msdasql.dll because I've got
version 2.71.9030 installed, but it looks like VS 6 wants to install
2.0.3002.11 ...

Manually registering the file using regsvr32 may work.

regsvr32 <path>\msdasql.dll

I tried unregistering msdasql.dll, then replacing the one on my hard drive
with the one in the \SHARED\OLEDB directory of the VS install CD. When I try
manually registering I get 'LoadLibaray("msdasql.dll") failed - The specified
module could not be found.'

I assume this is caused by a missing/invalid dependency, which is probably
due to the fact that this msdasql.dll belongs to an older set of data access
components than what Win XP includes.

I guess I could start replacing all of the DLL's that msdasql depends on,
but I don't know if I want to "downgrade" my MDAC....

Any other advice?

Rick,

Download a tool called Dependency Walker from http://dependencywalker.com.
You will be able to use this tool to see if there is a problem with one of
the dependencies of the file.

Feel free to save the dependency log out, and send it to me. I will be
glad to assist in reviewing it.
