I was happily running malariacontrol using BOINC 6.12.34. Today, I received a message 'new version is available'. And downloaded BOINC 7.0.25.
Click downloaded file. When installing, the package boinc_7.0.25_windows_intelx86.exe extracted to a temp directory. It tried to find BOINC.msi there, but did not succeed.
The extraction process did create 213b734.msi (no BOINC.msi), and upon retry (see below) presumably the same file under other random names. OK, I copied one of them to another directory and renamed it to BOINC.msi. Copied BOINC.msi back to the temp directory.
Retry to install, the installer still wants to know 'where is BOINC.msi'. Point installer to this file, receive an error 'the feature you are trying to use is on a network resource that is unavailable'. Now come on!
Did suspend antivirus still no joy. All the while tried to install with administrative rights, of course.
From my perspective, you should stay away from BOINC 7.0.25 for the time being.
I'm going to post this same message to some BOINC forum, but don't know yet if I have access there.
EDIT Forgot to tell: lost BOINC 6.12.34 in the process
EDIT Ok, have access to BOINC forum. As per http://boincfaq.mundayweb.com/index.php?view=119:
(1) repair BOINC 6.12.34 - download this version and reinstall. Don'forget to remove 213b734.msi that was renamed to BOINC.msi from temp directory.
(2) with 6.12.34 running, install 7.0.25.
(3) everything seems fine.
(4) phew, why on earth should I keep an .msi file when the application is already installed?
