SYMPTOMS
When you upgrade Microsoft SNA Server from version 3.0 to version 4.0, you may receive a pop-up message indicating that SNA Server cannot copy the Mfc42u.dll file to the \WINNT\System32 directory. A dialog is then presented with the options to Abort, Retry, or Ignore.



CAUSE
This message can occur if an application, such as Microsoft Visual C++ 4.2 (or some third-party application that has been written to use its own version of the Mfc42u.dll file), has a lock on this file during the upgrade process.



WORKAROUND
Stop any applications that may be running, and choose Retry to continue the upgrade process.
