kess connection not established-01

Possible reason:

1) Computer system is incompatible

2) Network connection

3) Software file is destroyed, need to reinstall.


  • Computer system requirement (OS): Better install ksuite on windows XP 32bit, we supply the perfect version for you at:


Why the user is supposed to install ksuite on XP pro, take kess v2 fw4.036 for example, before install it, you need to install Microsoft C++2005, if you change other XP system, C++ may be not 2015 version and lead ksuite fw4.036 not successfully installed.

Some user tested ksuite okay on Win 7 32bit, download at:
