When attempting to run a program that uses the THUM DLL version 1.0.0.5 or newer and you receive
"Runtime Error 53 File not found THUM.dll"
This is caused by not having the VC++ 2010 runtime installed.
The VC++ 2010 Redistributable package should be installed on target computers to provide the common libraries needed by VC++ apps.
