Dataman Forum

I am trying to use a Dataman-40Pro on a new computer with Windows 11. I downloaded the latest software (4.00) and installed it, but it cannot connect to the programmer. When I checked the Device Manager I could see it was showing up as an Unknown Device, and when I tried to update the driver, Windows gave me the following error:

"Windows found drivers for your device but encountered an error while attempting to install them.

DATAMAN-40PRO, Universal 40-pindrive Programmer

The install class is not present or is invalid."

How can I resolve this problem?

Hello jbyrne_ffe,

We are aware of a problem when software v4.00 is installed on a new system, the temporary solution is to install v3.99 and then install v4.00.

I have made Pg4uw software v3.99 available via our dropbox account here:

We think we have found the reason behind this situation and the problem will be fixed soon.

Apologies for the inconvenience.

After installing the v3.99 software it did not recognise the programmer initially, but I went to Device Manager, chose the "Unknown Device" and pressed the "Update Driver" button, and once I had done that it appeared correctly. I have now updated to v4.00 and confirmed that I am able to program a flash chip successfully.

Thanks for the prompt help.
