The problem is that the app_info.xml from Crunch3r's site permit to use the optimized client with work for 5.19 client, and BOINC mark and report all WU with version 5.19 of the seti client.

application version 5.19

Why this? Maybe a BOINC bug?

The problem is with the app_info.xml that is supplied by Crunch3r. It allows for versions up to and including 5.19 but since the section that references version 5.19 is the highest version on his list that is the section that is used by Boinc.

To correct this......
1) Set Boinc/Seti to "no new work" and crunch down your cache. Failure to do this will result in the loss of your entire cache.
2) When the cache is depleted, stop Boinc. Replace the information in the app_info.xml file with the following.

<app_info>
<app>
<name>setiathome_enhanced</name>
</app>
<file_info>
<name>setiathome_5.12_windows_intelx86.exe</name>
<executable/>
</file_info>
<app_version>
<app_name>setiathome_enhanced</app_name>
<version_num>512</version_num>
<file_ref>
<file_name>setiathome_5.12_windows_intelx86.exe</file_name>
<main_program/>
</file_ref>
</app_version>
</app_info>

3) Restart Boinc and set to "allow new work"

New work should be downloaded, crunched and reported as version 5.12.
