DW Spectrum® IPVMS Crashes

The DW Spectrum® Server and DW Spectrum® Client software will stop right after launching/starting.  When checking the Windows Event Viewer application, it was found that the applications ended operation on behalf of the Operating System (OS) due to “libeay32.dll”.

The file “libeay32.dll” is a dynamic library, part of OpenSSL, which is an open source solution for SSL/TLS connections.  This is used for any DW Spectrum® Client and DW Spectrum® Server connections, making it a necessary file to keep.

This article will outline how to update the version of the libeay32.dll file to resolve this issue.

Updating the libeay32.dll File

To update the libeay32.dll file:

1. Download and updated version of the libeay32.dll library.

• libeay.dll for 32-bit Windows
• libeay.dll for 64-bit Windows

**NOTE:  DW Spectrum IPVMS v4.0 and newer DOES NOT SUPPORT 32-bit operating systems.  The above link for 32-bit windows is provided for legacy servers only.

2. Stop the DW Spectrum Media Server from the Windows Service Tray.

3. Replace the existing libeay32.dll file (located in the DW Spectrum® file directory) with the new libeay32.dll file in the following locations.

• DW Spectrum® Client

• Desktop Compatibility Mode Installations

**NOTE:  If you are unable to locate the AppData folder in the file directory, click the View tab and enable “Hidden items”.

• DW Media Server

4. After replacing the libeay32.dll files, start the DW Spectrum Media Server.

5. Launch the DW Spectrum® Client application to test the changes as necessary.
