Hi Roman,

So far I did not install (yet) TeamViewer.
See attached he log file WinUSB issue.
It says:
00000044   620.21044922   [4460] nrComm Lib installs driver.
00000045   622.90209961   [4460] nrComm Lib Error:E0000203

Are the error code (e.g. nrComm Lib Error:E0000203) described somewhere?

Regards, Henny

Hi Roman,

As far as I can see I still haven't seen an answer from your side. Could you please at least explain what errorcode  nrComm Lib Error:E0000203) means such that I can find out what goes wrong?
Thanks in advance, Henny

Hi Roman,

Unfortunately running usbiodemo resulted in an error message saying "...\usbiodemo_64\usbdemo.exe is not a valid Win32 application".

Hello

Do you run it on 64-bit Windows ?

Hi Roman,

I've no 64-bit Windows computer here, only 32-bit Windows.
That means that I still have the same problem.

Could you please at least explain what errorcode  nrComm Lib Error:E0000203 means such that I probabbly can find out myself what goes wrong?

Regards Henny

Hello

We prepared 32bit version for you. Please try it:
http://deepsoftware.com/nrcomm/usbiodemo_32.zip

And upload here log file.

About your error  E0000203 and your log file.
It seems like you did not use TnrLogFile component and I can not understand how you can get this error.
Please try our demo. It should generate more detailed log.
