The Gotourl.exe is part of the fix. It was not there in the original UFT 2.x. The first time you unzipped the file, it was added and then you replaced it each time you unzipped again which is ok as you are replacing the file with the same file.
I think your porblem is not in the unzipping of the admin.zip. You must edit the "pd.ini" file as shown in step 3. To do this, doulbe clidk on "My Computer" on your desktop, then double click on the "C" disk drive and then double click on the folder where UFT is installed (normally "UFT"). Scroll down until you find pd.ini or just "PD".
Double click on the file and it should come up in wordpad or some editing program.
The first few lines may look like this:
[Palladium Server] IP=www.palladiumnet.com
[FTP Server] IP=www.palladiumnet.com
Chance them to look like this:
[Palladium Server] IP=www.uftree.com
[FTP Server] IP=www.uftree.com
Leave the rest of the file the way it is and save the modified file.
