Are you guys having a laugh? Would you like me to list every hotfix and microsoft product installed? I have net 1.0 + sp3 I have 1.1 + sp1 I have installed all of the MCE updates, I then install Net2.0, when I go to run MCE it comes up with an error, but restarting it fixes this... If I didnt have .NET 1.0 SP3 or .NET 1.1 SP1 I would have said... It doesnt work at all...
