I just tried out a beta version of BOINC (5.1.2) and now I would like to go back to the current Recommended (4.43). But when I attempt to install 4.43 the install process stops at the final step with a "Nothing to install" message.

How does one install an older version of the BOINCManager GUI? I'm running OS 10.4.2.

Delete all the old files, and then go here to get the optimized versions to install.

Hmm, I should clarify my question:

How do I install the lower-numbered version without losing all my settings and history on this machine?

Before I started this thread I had already tried deleting the main BOINCManager app file before running the 4.43 installation, but that didn't help - I still got "Nothing to install."

The only other files I know about to delete would be those in the /Library/Application Support/BOINC Data/ folder. Deleting that would certainly erase all of the history for the statistics graphs. I realize that would be just a cosmetic loss, but surely there must be a way to install a lower-numbered version of the app file without having to delete all of those data files, too. Maybe there are just particular files in that data folder which one should delete, instead of "all files"?

Try going into your /Library/Receipts folder and deleting the BOINC.pkg file.
I believe the installer is saying there is nothing to install because it thinks it's already installed.

Good Luck ;)
