Solid Works crash after run Flow Simulations

Hi,

I have just installed Solid Works 2012 SP 5.0 64 Bit on my PC with these specs:

- Core i3 3.3 GHz

- 8 GB DDR3

- Radeon HD 7770

- Win7 64 Bit

After I prepare my works for Flow Simulations (with wizards), and I click "Run" button, Solid Works just crashed and pop out notifications like this:

Why this error show up? How can this error solved?

Any advice please?

Thanks in advanced...
