During installation attempt process it says that "The feature you are trying to use (which feature?!) is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package "BOINC.msi" in the box below." So I am searching for fileneme "boins.msi", entering founded path "c:\WINDOWS\Downloaded Installations\{C1034FAD-D4EF-4A25-AE4D-AC7FD8254F05}\BOINC.msi", i.e. I am searching for boinc.exe on this path, but it doesn't work! "The file C:\WINDOWS\bla-bla-bla\BOINC.msi" is not a valid installation package for the product BOINC. Try to find the installation package "BOINC.msi" in a folder from which you can install BOINC." Of cource, in the folder from which I am trying to install BOINC there is now such file.

What to do?

First, 6.2 is still in Alpha testing. The correct forum for problems is the boinc alph mailing list.

In this case, you might try deleting the msi file from all your caches and try the download again.
