If I am setting up a new computer with 6.2.19, what directory do I have to copy the ak v8 files to?

You want the BOINC Data folder (well, the project's subfolder in the data folder), but where that folder is depends on the operating system you're using.

There's a list of the default locations for various OSs in The Big BOINC 6 Answer Thread. Note that on some operating systems (Windows Vista in particular), the data folder may be hidden by default.

I adapted the How to install a Seti optimized application FAQ for use with BOINC 6 some time ago.

There are a couple of things which haven't been updated in the installation FAQ yet:

When you first attach a new computer to the SETI project, you'll be allocated at least one WU, and the stock application to run it. That initial WU might be MB, or it might be AP, or if you leave it alone for a few minutes, you might get some of each.

1) Initial MB WU
This will branded as v6.03, and the standard AK_V8 app_info.xml file hasn't been updated to reflect this. You need to edit this file (using Notepad), and find the section

    <app_version>
        <app_name>setiathome_enhanced</app_name>
        <version_num>528</version_num>
        <file_ref>
           <file_name>AK_v8_win_whatever.exe</file_name>
            <main_program/>
        </file_ref>
    </app_version>

Copy and duplicate this entire section, and update the version number in the new section:

    <app_version>
        <app_name>setiathome_enhanced</app_name>
        <version_num>528</version_num>
        <file_ref>
           <file_name>AK_v8_win_whatever.exe</file_name>
            <main_program/>
        </file_ref>
    </app_version>
    <app_version>
        <app_name>setiathome_enhanced</app_name>
        <version_num>603</version_num>
        <file_ref>
           <file_name>AK_v8_win_whatever.exe</file_name>
            <main_program/>
        </file_ref>
    </app_version>

2) Initial AP WU
Installing the AK_V8 application on its own will destroy your computer's ability to handle AP tasks: any AP task which has been downloaded, whether it has started running or not, will be returned as a client error.

If you want the ability to crunch AP tasks as well, you need to download and install the optimised AP application too, and splice the two app_info.xml files together - incorporating the updated MB version number as well.

Thanks all. I think I've got it now.
