Re-posting what ReligionX sent on Trac:

When I saw a new version was available at boinc.berkeley.edu, I downloaded it. I closed my application.

Click Install to being Installation -> Install -> The feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert the "World Community Grid - BOINC Agent" disk and click okay.

Cancel -> Error 1706.No valid source could be found the for the product World Community Grid - BOINC Agent. The Windows Installer cannot continue.

Add or Remove Programs -> World Community Grid - BOINC Agent -> The feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert the "World Community Grid - BOINC Agent" disk and click okay.

Cancel -> Error 1706.No valid source could be found the for the product World Community Grid - BOINC Agent. The Windows Installer cannot continue.

I ran the Windows Installer Cleanup -> World Community Grid - BOINC Agent [5.10.45] -> Remove -> Exit -> Reboot. As far as I can tell the Windows Installer Cleanup did absolutely nothing. When I hit Remove, it is still available for me to remove. The icon did not come up as BOINC.msi or a corrupt icon.msi.

Upon attempting to install a new or old version, the same thing happens. I am currently unable to run BOINC.

I am running Microsoft Windows XP Home Edition Version 2002 Service Pack 3.

This is me.

- Download WCG BOINC 5.10.45.
- Do a repair installation with it. This will fix the corrupt MSI file.
- Uninstall using Add/Remove Programs.
- Install the next BOINC.
