Rapetier has stop to run on 64Bit Win 7 (no replies)

Hi,
After installed Repetier-Host Windows 0.90C on my laptop, it stop working and can't enter the software interface.

I also try Repetier-Host Windows 0.84, it also has same problem.

Here is my PC info.

Lenovo G585
Win 7 Service Pack 1, 64 Bit

What critical services/software need on OS before install Repetier Host, since I always meet same problem on different PC on Win8, Win7, XP or Vista.

Thx.
