Program doesn’t start using inventor 2010 on windows 7 64 bits

Hi there guys,
I need some help with this.
I use a computer that runs on windows 7 64 bits.
I work using inventor 2010. Sometimes, the program doesn’t wasn't to start and shows me this error.
I tried to restart the computer, but I still get the same error message.

However, a friend of mine was able to install it to his computer without any problem. So, is there a way to repair this?
Thank you very much for your help.
