This article was previously published under Q318730

rpcss.exe
The procedure entry point ??_U@YAPAXI@Z could not be located in
msvcrt.dll
-or-
When you try to start a program, you may receive an error message similar to the following:
Application.exe - Entry Point not Found
The procedure entry point ??_U@YAPAXI@Z could not be located in the Dynamic Link Library MSVCRT.DLL
This behavior may occur if you install a third-party program that replaces some of the Windows NT 4.0 dynamic-link library (DLL) files with those of a different version.
This behavior occurs when mismatched DLL files try to reference a function in Msvcrt.dll.
To resolve this issue, replace the following DLL files with new copies from a Windows NT 4.0 computer that is updated to the same service pack level and that is running the same version of Microsoft Internet Explorer as the Windows NT installation on which you experience this issue:
Msvcrt.dll
Msvcirt.dll
Msvcrt20.dll
Msvcrt40.dll

- If you do not have access to another computer that runs Windows NT 4.0, install a new copy of Windows NT 4.0 to a different folder on your computer.For additional information about how to do this, click the article numbers below
