(Sorry, if this was already written anywhere here...)

After really many years with SETI on a variety of computers :-),
since several weeks my BOINC/SETI-application is corrupt.
This happened when trying to update (now v7.6.22 x64 is here, but it would never work..., think this is the mis-installed newer version, if I remember correctly).

When the update won't work anymore, I had tried to uninstall and clean (registry) as detailled I could, to get a clean system for a reinstall of the actual version, but without success.

What I do need now, is a precise instruction to come to a new installation, perpaps on a fully BOINC-clean system(?) and to start it all from scratch.
My account-data do exist, and I want to go on again! :-)

Would much appreciate a practical help from you...!

When you try to install BOINC 7.6.22, do you get an error message?
If so, what kind of error message do you get?

Sorry, last trials were weeks/months ago.
I cannot remember this.
Maybe, the actual program version is newer, would take, of course, this one...

So, download https://boinc.berkeley.edu/download.php BOINC 7.6.22 and try to run its installer. When you get an error message, write it down and tell us about it.

Sorry for being late about this...!

Now the results of my trials in short:
Note: BOINC is/was not installed on C: because of space problems, but installed on D: (this had worked before without problems)

- Deinstalled existing but not working version 7.6.22
- Additional deletions manually:
d:\programdata\boinc (\slots and \projects had been empty)
C:\Users\admin\AppData\Roaming\BOINC
C:\Users\boinc_master
C:\Users\boinc_master.WIN-7

After boot and download of BOINC 7.6.22 again as suggested
- New installation:
with program dir: d:\programme\BOINC and data dir d:\programdata\BOINC\
- ... allowed for all users

Then:
- Old/new error on autostart:
BOINC-Manager window says: cannot connect with a BOINC Client
(And all menu options there not active; repeatedly same message...
including no "Add project"-prompt
This had been the result before, with several installations...

- Service checked, is installed and working
- ?Firewall? %programfiles%... for the two programs changed to literally path
-> no change of symptoms
- Checking the router (Fritzbox 7390): no hints

So, all this is a repetition I have had before in several installation trials
in Feb/March.

I hope this shows any hint or way to reactivate SETI-crunching. :-)

Thanks in advance!
