I have installed the software in my PC i don't feel any problem.. can you try a different version of AV Ajay<contact@nospam.com> http://www.8051projects.net/forum-t1700.html i mean schematic diagram for avr. ok ajay, now i can install the program. Thanks. the problem is the file that i download was corrupted. thats why i c 4y133<ayie.nm@nospam.com> http://www.8051projects.net/forum-t1700.html ok..for AVR its very simple..everything is labeled..
