KTAG 2.25 got an error ” Connection not established”, shown as below.

Possible reason:
1) Give 12V power adapter
2) Computer system is incompatible
3) Network connection
4)Software file is destroyed, need to reinstall Solution:
Computer system requirement (OS): better install ksuite on windows XP 32bit,we supply the perfect version for you at:
win xp: https://share.weiyun.com/5VP1mxN pass: 1zkboe

Why the user is supposed to install ksuite on XP pro. take kess V2 fw4.〇36 for example, before install it, you need to install Microsoft C++2〇〇5, if you change other XP system, C++ may be not 2015 version and lead ksuite fw4,〇36 not successfully installed.
Some user-tested ksuite okay on Win 7 32bit
win7: https://share.weiyun.com/59Noy7p pass: 0awk7b
2) Network connection: Do not connect to the network connection, otherwise ksuite may be locked.
3) Reinstall ksuite (Please note: in the CD, there are one video demo for instruction)
