Everytime BOINC tries to DL this app, I get an answer like this:

15-9-2010 0:00:57|Milkyway@home|Backing off 1 hr 25 min 24 sec on download of milkyway_nbody_0.06_windows_x86_64_ss2.exe.

This is my appinfo:

<app_info>
<app>
<name>milkyway</name>
</app>
<file_info>
<name>astronomy_0.20_SSE3.exe</name>
<executable/>
</file_info>

<version_num>19</version_num>
<file_ref>
<file_name>astronomy_0.20_SSE3.exe</file_name>

</file_ref>
</app_version>

<app_version>

<file_ref>

<main_program/>
</file_ref>
</app_version>

<app>
<name>milkyway_nbody</name>
</app>
<file_info>
<name>milkyway_nbody_0.06_windows_x86_64_SSE2.exe</name>
<executable/>
</file_info>

<app_version>
<app_name>milkyway_nbody</app_name>
<version_num>6</version_num>
<file_ref>
<file_name>milkyway_nbody_0.06_windows_x86_64_SSE2.exe</file_name>
<main_program/>
</file_ref>
</app_version>

</app_info>

I have tried these versions, but all with the same result:

milkyway_nbody_0.06_windows_x86_64.exe
milkyway_nbody_0.06_windows_x86_64_sse2.exe
milkyway_nbody_0.06_windows_x86_64__sse2.exe

What can be the reason?

Hi, the app has just been updated to v0.07. Please note the two underscores between '64' and 'sse2'.

At first, your tips worked very wel. Thanks.
But I have another strange thing on a 32 bit computer.

In the appinfo file stands this:

<app>
<name>milkyway_nbody</name>
</app>
<file_info>
<name>milkyway_nbody_0.07_windows_intelx86__sse2.exe</name>
<executable/>
</file_info>

<app_version>
<app_name>milkyway_nbody</app_name>
<version_num>7</version_num>
<file_ref>
<file_name>milkyway_nbody_0.07_windows_intelx86__sse2.exe</file_name>
<main_program/>
</file_ref>
</app_version>

BOINC says: at startup,even after several reboots, incl. a complete powerdown:

15-9-2010 17:28:41||[error] No URL for file transfer of milkyway_nbody_0.07_windowsx86__sse2.exe
15-9-2010 17:28:41|Milkyway@home|[error] Can't initialize file transfer for milkyway_nbody_0.07_windowsx86__sse2.exe

15-9-2010 17:28:41||[error] No URL for file transfer of milkyway_nbody_0.06_windows_x86.exe
15-9-2010 17:28:41|Milkyway@home|[error] Can't initialize file transfer for milkyway_nbody_0.06_windows_x86.exe

And keeps looking for an other file than is downloaded en written in the appinfo file.

How is this possible and more important: how can I resolve this problem?

My guess is that your client_state.xml ist corrupted or something else defining the projects parameters. The app_info content you posted looks allright, if these are all entries for milkyway_nbody. However, BOINC is asking for three files of which none is the right one.

I'd say save the app_info.xml, detach the project, reattach again and throw the app_info.xml into the .../projects/... directory again. You might want to download milkyway_nbody_0.07_windows_intelx86__sse2.exe manually, too.

Detaching and reataching fixed the problem. Thanks.
