When you try to run a Visual Studio .NET-based MFC application on a computer that is running Windows NT 4.0 Service Pack 5 or earlier, you receive the following error message:
The dynamic link library OLEACC.dll could not be found in the specified path
The MFC dynamic-link libraries (DLLs) that are included with Visual Studio .NET require that the Oleacc.dll file be installed on the target computer.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This hotfix may receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next Microsoft Visual Studio .NET service pack that contains this hotfix.

This problem does not occur with Windows NT 4.0 Service Pack 6a or later because Service Pack 6a installs the Oleacc.dll file. Microsoft highly recommends that you install Windows NT 4.0 Service Pack 6a to get the latest updates for Windows NT 4.0.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
