For those of you having problems installing here are the details of how to generate an Install.log file:-
Please create a "C:\Temp" directory and copy the "PicoScope6_r6_3_43.exe" download file into it. Make sure the PicoScope is not plugged into the PC. Now go to the Windows "Start" button, then select "Run" and in the command line box copy and paste the following:-
C:\Temp\PicoScope6_r6_3_43.exe /v"/L install.log"
Click "OK" and PicoScope6 will start to install in the usual way. At the end, whether the software has installed properly or not, there will be an "Install.log" file in the "C:\Temp" directory. Please email that file to me and we can then see what has gone wrong with the firstname.lastname@example.org
