Interop Dll Problem

[pratibha14]

hi,
I have to add third party dll. But it returns the following
FileNotFoundException:
"File or assembly name 'TimesTen Provider, Version=6.0.3000.0,
Culture=neutral, PublicKeyToken=421da04c8fc1f667', or one of its
dependencies, was not found. "

Also its Interop dll is not created. When i check the dll using Dependency
walker software (

http://www.dependencywalker.com/)

it returns following
errors and warnings:
"Error: At least one required implicit or forwarded dependency was not
found.
Error: At least one module has an unresolved import due to a missing export
function in an implicitly dependent module.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing
export function in a delay-load dependent module."

So where is the problem occuring? Is dll is not correct or am i using it incorrectly?
Thanks in advance
