After reading some of the forum, I've found my problem (roll-back at the end of software installation) to be quite a common issue. However, the solutions provided do not work for me. I'm using a laptop with Windows 2000 and an ADC-100 converter. PicoLog used to work perfectly until I had to reinstall the software and got a driver error (pico.sys not found). Re-install is interrupted and gives a roll-back without mentioning why. There's only one LPT port on the laptop, connected to the ADC-100. Disconnecting the converter does not solve the problem and there are no other parallel ports on the machine. Any suggestions are welcome.
Thanks in advance,
