Today I tried upgrading from Boinc 6.6.20 to 6.6.28!
I selected "download Boinc" and received the updated version.During install I noticed it was migrating files and thought that was strange. When I restarted Boincmgr, it asked me to attach to a project. All of my projects and progress to that point had been wiped out, no recovery. The files were not "migrated" they were erased. I quickly noticed that the new version was the 32 bit version which apparently is the only one downloaded from the basic selection. I remember that I had gone to the "all versions" part before to find the 64 bit version. My error there, but I do wish that the install had asked me if I really wanted to replace a 64 bit version with a 32 bit one. Some of the projects did have 64 bit clients, not sure they all did. Anyway I am not really sure that the answer was to wipe them all out. So I post this in hopes that someone else won't make the same mistake. John

Some of the tests that are preformed in Boinc Alpha group are upgrade tests. Because of 32bit or 64bit files are placed in different directories. What I would recomend if if you have a copy of Boinc 6.6.20 that you unistall 6.6.28 which should revert you back to 6.6.20. Then reinstall 6.6.20,which should correct the problem. Then download 6.6.28 64bit, and go from there.

Is there any way for the download site to check what bits the OS is running on instead of the browser? Windows XP x64 defaults to start the 32bit IE. No 64bit FF available (unless you install an alpha from 3rd party). Don't know about other browsers (Opera, Chrome, Safari, etc.).

Default Firefox is 32bit, they don't have a 32bit version (not before 4.0).
There are 3rd party Firefox 3 - 64bit beta's available.

Now as for the OPs problem... your original BOINC Data directory is probably still on your system. Check your 64bit specific directories, where a 32bit program can't read. The BOINC Installer never deletes the Data directory. The 32bit BOINC Installer can't read those 64bit specific directories either. (64bit can read 32bit data, not the other way around!)

The migrating you saw was probably from an even earlier BOINC directory that was still on your system. You may want to do some rigorous cleaning.

On previous upgrades of BOINC, I've tried to place the data files in a different place than recommended by BOINC. BOINC decided to place it in a 3rd folder. I got the same thing. BOINC couldnt find my projects.
Search for the files and I'm sure you'll find them then just move them to where BOINC thinks they are supposed to be

I will reply here and try to cover all of the prior posts.
The data dir was \Program Data\Boinc and the projects directory under that was cleared out except for the placeholder file. I did reinstall 6.6.20 (x64) after I had looked everywhere I knew to look for the data, it also wanted to attach new projects as there were none to use. This had been a new install using Windows 7 on an Intel I7 and DFI 64bit motherboard, no prior 32 bit Boinc files existed.
The migrating was very fast (watched the bar move quickly to 100%) then there was a long "pause" where nothing appeared to happen before it said the install was successful.
As I recall I was shown the install directories (both pgm and data) when the update began which were the same as previously used.
I am back running, but as everyone knows I lost all that(unreported) credit. The work units that I can not report back with will be reissued, but others depending on me to do my part will wait longer for the validation because the work units will be delayed in completion.
Such is luck. John
