Hi Juan,
I uninstalled the previous version as usual and run the PI 1.6.1 installation file. Everything went OK but I cannot start PI. A window pops up with the following message:
"No se encuentra el punto de entrada del procedimiento freeaddrinfo en la biblioteca de vĂnculos dinĂ¡micos WS2_32.dll"
My OS is Windows 2000 and the installer is: PI-win-x86-01.06.01.0625-nsi-20100727-c.exe
Many thanks,
Pere
