Solidworks Flow can not save or run

Hi all,

currently i use Dell M4800 i7 2.4Ghz, AMD Radeon R9 M270x video card with Win7 64 bit.  But i can not save or run Solidworks flow. For Solidworks simulation, there is no problem. I can run static test as normal.

Could anyone please kindly support?

Tks,
