RIO PC Configuration Utility won't start

I have installed the "RIO PC Configuration Utility" several times on a WIN7 and WIN8 computer unsuccessfully and receive the following "Unhandled Exception Occurred" each time on both computers. The text of the error is:

An error occurred creating the form. See Exception.innerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)

there is more but I can't copy and past it.

NET Framework is up to date on both machines.

thanks for any help.

You can do a screen capture by pressing the alt + prtScn. The prtScn is located near the top right side generally near the backspace key on the keyboard.

Then open up paint or a microsoft word document and do a ctrl + V. The screencapture should populate.

Does this error occur when opening the utility or when you connect the Rio to the utility?

I have v.9/24/13 date code in mine and it does open without that error as does my laptop with windows 8 in it. I have not yet connected the Rio to the pc.

One other thing to point out. Before this was installed, I had made sure the computer allowed me to force unsigned drivers.

If you haven't done so, try uninstalling the utility, and then set up your computer for it to allow unsigned drivers, and then reinstall the utility.

attached is a screen capture of the errors i receive on the Win7 machine. They look like the same ones i get on the Win8 machine. i haven't had time to look into the potential unsigned drivers problem.

Try this installation file. It's not much older, but it is what is installed on my pc.

thanks --- your older rendering of the Configuration Utility works on both the Win7 and Win8 machines.

I did uninstall the one I had and upgraded to the latest and that opened up and worked for me. The one I uploaded here may have installed the missing file(s) the newest one was looking for and did not get removed in the removal thus allowing for the latest one to install properly.

I installed the new version over the older version of the Configuration Utility and it works for both Win7 and Win8. Thanks for the help.

I'm having the exact same problem with v. 1.0, 27 september 2014. I have tried running it as administrator, but that doesn't help.

The older version works though. Shame that the new version still isn't fixed for Win8.
