That's odd. I did that and it installed OK (Picolog for Windows Release 5.21.5) but on start up it gives the error message <Driver 'adc1132.dll' not found>. Then when I try to load the data file it gives another error message <ADC-11 LPT1,lle Driver 'adc1132.dll' not found> and closesd down.
I think we're getting towards a solution. I found folder Pico Technology\Pico Full under Program Files (x86), not under Program Files. And it contains several .dll files, but not adc1132.dll. Does that suggest a solution?
I will say though for viewing the data that should be no problem installing the software on a 64 bit machine. So you would have to install the software for another product and then open the file that way.
