I get this error message when shutting down my PC (Win7 64-bit), with BOINC 7.2.42 installed as a service. It seems to be basically the same error reported earlier, http://boinc.berkeley.edu/dev/forum_thread.php?id=8833&postid=51923#51923 but I just wanted to check it out with the current released version of BOINC.

I looked in the BOINC program folder, and no such file exits, so it is not surprising that it is not found.

Forwarded to development.

OK, one thing you can try to do is uninstall BOINC, then reinstall it. Then check if the file is still missing. Could someone or something have deleted it?

OK, I just re-installed BOINC 7.2.42 x64 as a service (all users, no screensaver), and the "boincsvcctrl.exe" file was in fact there in the program folder as it should be. I have re-booted a couple of times with no problems, so it seems that everything is working fine thus far.

I think that file may have been removed by an AV I was using (Bitdefender free), which has a tendency to block files it does not like, and maybe removed it without alerting me, though that is a bit of speculation on my part. However, I am now back to using MSE with the appropriate exclusions to the BOINC folders, and hopefully that will prevent it from happening again.

Thanks for your input.

Great, thanks. I'll let the developer know.

I have found the reason for the missing file (boincsvcctrl.exe). It is not due to the AV, but it is missing on the initial install when I upgrade (or downgrade) from another version. In order to get the file, I have to run the installation a second time and do a "repair"; then the file gets installed. This may not be a problem on clean installs, I have not checked that.

Also note that the problem is apparently just for service installs. I have installed 7.3.11 (for example) as a non-service on a couple of WinXP machines with no problem getting boincsvcctrl.exe installed in the BOINC program directory.

And my first success with 7.2.42 noted previously was after having totally removed 7.3.11 from a Win7 64-bit machine (including deleting registry entries), so I guess I have tried a clean install, and it works OK there too.
