Problems with the installation of NX 12.0 documentation

Hi,

I was trying to install the  documention file of NX 12.0 recently, but when I press the key F1, it displays an error webpage after the installtion as below:

 If I broswer localhost:8282 directly, it shows another error webpage:

I've tried several times to uninstall and reinstall the PLM DOCUMENTATION SERVER and the Documentation file, but it still doesn't work. 

Has anyone what causes the problems and how to fix them? Any information is appreciated.

Thanks in advance!
