I have just finished formatting/re-installing xp on a friends Pc and when I attempt to install a piece of software it gives me errors and has to abort. I get failed to read data from CD. So I tried copying the file via my network onto this Pc and then installing it. Same thing or corrupt file. So I installed it via the network from the other Pc and it works fine that way. I have had to do this with nearly every piece of software so far. Could this be due to a bad instll of Xp? I have never experienced this problem before so I don't want to have to uninstall and try again if I can help it. If it is a small file like winrar or daemon tools install it works fine, but anything that takes a while will generally not work. Thanks in advance for any help given. Andrew.
