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.
To update the libeay32.dll file:
**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.
C:\Program Files\Digital Watchdog\DW Spectrum\client\<CURRENT VERSION>\libeay32.dll
C:\Users\<USERNAME>\AppData\Local\Digital Watchdog\client\default\<CURRENT VERSION>\libeay32.dll
**NOTE: If you are unable to locate the AppData folder in the file directory, click the View tab and enable “Hidden items”.
C:\Program Files\Digital Watchdog\DW Spectrum\MediaServer\libeay32.dll
