Many thanks for your reply.
This problem aiso occurred when I attempted to instal a programme for Winamp Codex.
Before I installed dot net, I first recieved Parsing error"Error parsing windows\system\config\machine config
Parser returned error0x80070003"
The Failure to load etc message is behind this one.
When I installed dot net,the first message sodded off,and only the failure one appeared.
I checked Windows systems and the config file is not there
The only config file is in Windows and is a general config and seems to be obsessed with midi players.
I hope this information has not just muddied the waters even worse,but,apart from that,I know nuzzing.
Thanks in advance,
Crom
