Reading the Manual carefully solved problems. Updating Windows 7 had corrupted a file so that had to be sorted as well.

Thanks for your help!!

I have an TC-08 with RS232 and an ADC-11 with 25 pin D connecter.

Hi Martin, its Windows 7 64bit.

At present I'm clearing out OS(C) also installing the latest Windows 7 updates, to May 2016, then I'll re-install PicoLog, and try again.

:oops: I've installed PicoLog + 64 bit SDK (in case it installed the hw drivers), windows 7, Intel i5, laptop In "Converter details" the responses are Driver 'UsbAdc11.dll' not found Driver 'adc1132.dll' not found Driver 'usbtc08.dll' not found Driver 'tc0832.dll' not found Any suggestions?
