Installer problem: '-115 error'

Problem/Question/Abstract:

I have reinstalled my system (NT 4.0 WS), but now when trying to install my Delphi 5 Professional I get this message:

**************
Setup has detected a -115 error while attempting to copy files.

This can be caused by a file being un use while trying to install.

Component: Program Files\Main program files\debugger
File: C:\Program Files\Common Files\Borland Shared\Debugger\bordbk50.dll\bordbk50.dll
Error: -115
**************

Answer:

Open a command-prompt. Change to the 'C:\Program Files\Common Files\Borland Shared\Debugger' directory and type the following command:

regsvr32 bordbk50.dll
