I've been running BOINC on my Windows 7 machine for a good while myself and have had no trouble running various projects. I've also gotten a number of beta test units from WCG.

Dunno... need more data. Getting a 35% 'Error' rate on the HPF2 project with the machine (AMD 64 X2 4200+, 2GB) on which I have Win7 beta installed.

Manual data mining from Results Status shows
26 results from that device on that project...
15 Valid (57.6 %)
9 Error (34.6 %)
2 Pending (7.6 %)

The errors are all the same:

<core_client_version>6.2.28</core_client_version>
<![CDATA[
<message>
Incorrect function. (0x1) - exit code 1 (0x1)
</message>
<stderr_txt>
ERROR:: Exit at: .\dock_structure.cc line:401

</stderr_txt>
]]>

0 errors from the other projects it's been running (out of 16 Valids showing in Results Status).

And it is still the beta - probably DL/burn the RC this weekend and install it sometime next week... will try it on a single core then, too.

I do have a few (3) errors from HPF2 on other devices, but those were caused by me.

Hmmmm... so, you're advising everyone that's running the Windows 7 betas and the release candidate to either not crunch HPF2 or else use BOINC version 5.10.45 as a service?
i.e. rather than help develop the BOINC 6.x betas so it will (or at least 'might') work better with Win7 (and vista).

Windows 7 is coming. Probably by the end of the calendar year.
I've managed to avoid vista totally, but from what I've seen of Win7, so far, in my opinion it's better than vista *and* XP. Unless MS goes way overboard on pricing, I think it will see far-higher acceptance levels than vista has achieved; If they do go overboard on pricing, I (and perhaps many others) will go with Linux when XP support ends.

Darn... no penquin smiley.

Heh... did I catch you early in the morning, Sekerob? ;-)

It's hard to read words from your lips when you don't say them.
i.e. that's the first mention of IF they fail that I see. I wasn't arguing with you.

I don't find a copy of dock_structure.cc on any device here so I have no idea what's on line 401.
