ParaView and Tecplot 360 'has stopped working' on windows
 

hi guys,
I got a trouble on my new computer about the ParaView and Tecplot 360. My new computer has 64 bit arch and 64 bit Win7. After I installed these two software, I can not open them. Both give me error message of '... has stopped working'. I tried to change the 'Compatibility' in 'Properties'; unfortunately, it does not work.
My old computer also has 64bit arch and 64 bit win7, and all these two software execute well on it. Therefore, this confuses me a lot.
Any help will be greatly appreciated. ^_^

Alan
