Install fail with repoutil.exe problem

I fail many times on the exception of repoutil.exe.

I install db in one server and all other services in another. With success of precheck but fail with the exception of repoutil at almost the last step.  From install log I found repoutil executing with db connection params. I also found some article said it might have relation with msdtc with firewall question. And I tried after turn off the windows firewall but still fail.

Anyone have meet same question and know how to resolve?

Thanks.
