DLL Init Error: Windows unable to load the estapi.dll

[Bobbie Jean]

After finding and putting the needed windows DLL in the system folder, and rebuilding my project, now I get the error: DLL Init error: Windows unable to load DLL "C:\pathname\estapi.dll". The estapi.dll is resedent in the specified directory. Thank you.

This usually means there is another DLL or file that this DLL is dependent on that is missing. You can use the Microsoft Visual Studio tool Depends to check what dependencies that DLL has. Most likely you will find it depends on another DLL that is missing. If you don't have Visual Studio, you would have to find another tool to check the DLL dependencies.

I used the tool Depends. It identified the dll I was missing. I put the required dll in the system folder. Rebuilt the project and ran. The error message reported was: "DLL INIT Error: Windows cant open the DLL." I just figured it out! the two MS DLLs were mismatched. Once I put both from NT onto 95 it worked. Thanks so much!
