From Old To New

You'll have to delete the checksum file as well (once you've moved it all over).
This is how I do it:
1.) I copy the CoHUpdater.exe to the desktop (Do not create a shortcut, copy the actual file there.)
2.) Run it and tell it where you want to install. Once it starts downloading, go ahead and close it.
3.) Copy the contents of your old CoH folder into your new one.
4.) In the new folder, delete the checksum file.
5.) On your desktop click on the City Of Heroes shortcut and you should be good to go. It should verify your files.
You can remove the CoHUpdater.exe from your desktop after that.
Hope this helps 
We'll see....
Giving it a try now. Is it going to care much about coh.patch file?
Edit: Seems not to have. Thanks a bunch, man!
Not a problem. Glad I could help 
We'll see....
A friend of mine had City of Heroes installed on his old, pre-Vista computer. When he upgraded his computer, he moved on to Windows 7. What we have now is an Issue-16 viable copy of CoX, sitting on his slave hard drive, but won't run.
So; guidance, oh gurus. I thought the plan was that you run cohupdater.exe, then, after it's created the correct directory, you close cohupdater.exe, go back through the old copy of the game, copy all those files to the new directory, and then startup cohupdater.exe again.
However, it seems it doesn't work. So, is there some trick to this? Or is the only solution to simply let it re-download? I'm not so familiar with Windows 7 that I would try tooling around and getting it to work on my own.
