--- Comment #2 from Tiffany di Vita neodynamite@gmail.com 2008-04-08 14:50:16 --- You don't need Ultima Online to get to, and observe, the stage where the crash is occurring. To install UOAssist, you will be prompted to specify a directory where the UO files are located. If you create two random files called UOPatch.exe and client.exe this will be sufficient. It'll then open a window and attempt to load the URL at which point it'll crash.
To test functionality beyond this point of crashing, you will however need UO installed. The UO installer is actually available on EA's FTP servers:
