Loading module SGEDRV.dll failed

when I double clicked on "My Computer" I received the following
error message:
Fatal Error: Loading module SGEDRV.dll failed (Error #126).

I hit "OK" and the same message appeared again. I hit OK again and
When I clicked "OK" my screen went black and then my desktop reappeared with
no icons.

解决办法：
Right Click om "My Computer" and select Properties | Advance Tab | Environment Variables.

Select Path Variable in the lower part of the box by clicking on it and add C:\Program Files\Utimaco\Safeguard Easy

原因：我在配置java的path的时候没有注意到这一点。由于path环境变量的原因，找不到那个文件了，所以报错。在path中加入Safeguard Easy的路径就好了。
