When I try to install BOINC on my Win 7 Home Premium machine, the install wizard starts, tries to run the Computing Space Requirements window, but I get an error "1327.Invalid drive m:\". At this point the wizard aborts with an incomplete installation. The Win 7 PC is on a LAN with several other Windows machines, one of which is my file server (network drive M:). I've tried removing the mapped drive, disconnecting from the LAN, restarting, all to no avail. The manager is currently installed on another PC, but it does not matter if that PC is online or not. Any help on this would be appreciated.

Please see this FAQ for options on fixing the problem.

Error 1327 is slightly different from the common .msi woes.

There are a couple of workrounds in the (open) bug report: trac ticket [trac]#815[/trac], but unfortunately both involve editing the registry - either

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders

or

HKEY_LOCAL_MACHINE\SOFTWARE\Space Sciences Laboratory, U.C. Berkeley\BOINC Setup

The second one worked for me: change any references to M: in INSTALLDIR and DATADIR to C:, or some other valid local drive - that should give you control over the installer again, and you can make your own choices on the 'advanced' screen as normal.
