如果你的电脑是WIN7 32位或者64位的系统,你在安装WQI的时候 你可能会遇到 NOVACOM驱动无法安装(windows在线安装也查不到),还有JAVA系统无法打开JAR后缀的文件。(因为默认是压缩文件打开,可以自己先取消关联)
If your PC is WIN7 32BIT or 64bit. When you were getting install the app WQI.jar, sometimes your pc will not find the NOVACOM driver by it self. After that the WQI could not run properly. Now You should install the NOVACOM driver by yourself.
Here is the link for 64bit. NovacomInstaller_x64.msi - 4shared.com - online file sharing and storage - download 32bit is easy to find I think.

If you still can not open the ".jar" format file. First of all, release the relation between JAR and any WINZIP or winrar applications. Then open the WQI.JAR with the "JAVAW.EXE". You can search it in your pc.

If you still can not open it. Try to update your java platform. by this linkjava.com: Java + You find the 64bit version to install.Then try again.

If you still can not open it.(come on man.. what is the" if you".... but for real, I can not open it till next steps what I will write.)

1. Editing the Registry by typing regedit in the Start Menuís Search box)or (win+R)

2.Find the section: HKEY_CLASSES_ROOT\Applications\javaw.exe,
3.Go into the HKEY_CLASSES_ROOT\Applications\javaw.exe\shell\open\command,
click the "DEFAULT",
change the "value" to "D:\Program Files\Java\jre\bin\javaw.exe[red]" -jar "%1"[/red]
The upper value is mine. The "Value" may vary. But it doesn't matter.
You just need to input "-jar" to the proper position. it will be fine.
Please do full copy the red part without space.

If you still can not open.....
I don't know now NOW....
