According with seller website: http://us.rigol.com/prodserv/Waveform%20Generators/software/ latest version is 1.5.9 but your error crash refers to 1.6 version. It is possible you are running a beta version?

In mean time I updated my Win7to Professional version.
Then additional I uninstalled and reinstalled:
1) The old, original UltraSigma software with all NI-VISA and Measurement&Automation Explorer from National Instruments. Here original means the software received on the DVD together with the instrument. Is not working.
2) I updated the NI VISA and the driver to the latest version. Also I installed the lattes UltraSigma software. Sometimes there is no error and sometimes is the same. The error seems purely random. In fact I got more times error than normal working operation.

The process explorer from Sysinternals shows only ntdll.dll problems.

How should I trace this problem?

I have in mind only 2 more things:
1) The ugly and unwanted Windows repair by new installation.
2) I will try on a second PC with WIN7 64bits.

Here are the updates:
1) I have tried on a second PC with Win7 Pro 64bit.
I used the old original software UltraSigma and worked without any problems.
I upgraded to the latest version of UtraSigam and latest NU-VISA run-time and again works without problems.
2) Came back to my PC with Win7 Pro 64bits where I encountered the problems. I have tried  Windows repair install, but bad luck, I do not have the original DVD and cannot finish that. Besides the original DVD is Home Premium and I just upgraded to Professional with Windows Anytime Upgrade. I had only the option to scan for errors and try the repair at that level.
After reboot, the problem was still there, sometimes appeared and sometimes not.

By chance I found the cause. It was a conflict. It is unbelievable and unexpected.
The oscilloscope Rigol is connected to PC with USB cable.
I have other devices connected to the same PC with USB cables.
One of them is PICKit 3 programmer from Microchip.
I use the front USB connector from my PC for both, where 3 USB ports are present. I do not know how are these connected on motherboard and how the resources are allocated, but certain is that when I disconnect the PICKit 3 then I have no errors with UltraSigma software for Rigol control,
It is the same error if I use other USB ports from back of the PC.
When I plug in the PiCKit 3 and I start and try to use UtraSigma, then I get that ntdll.dll error.
It is a conflict in allocation the USB resources between these devices, somehow reflected in ntdll.dll
The solution seems to avoid usage and connection in the same time of the Rigol oscilloscope+UtraSigma and PICKit 3 to be connected to the PC.
