OldUnreal (Engine)

Well, I have U2 installed on my computer (included with Unreal Anthology). I want to download XMP, but it says I need to have the U2 disk with me... well, will the Unreal Anthology disk work as a suitable replacement for the actual U2 disk?

Thanks in advance

No, it will not. Those who packed Anthology were too lazy to make their own no-cd, so they used the one that was already out, so you can't use the UAnthology DVD for that. Instead, you have to download the Community Edition version that you can find in the essential files.
