#894 SpamBayes can't register correctly with Outlook 2010

Outlook (523)
Scott Hamilton

SpamBayes is listed as an inactive add-in and does not have a location. When attempting to add the add-in manual, the message "'C:\Program Files (x86)\SpamBayes\bin\outlook_addin.dll' is not a valid Office Add-in." appears.

    This is on a Windows 7 64bit machine running Outlook 2010 and binary 1.1a6.

    I am running Outlook 2010 (64-bit version) and I get this same issue. I assumed it was with Spambayes not being 64-bit compatible, so I manually compiled/linked this using Python 2.7 (64-bit) and the 64-bit version of the pywin32 for Python 2.7. This just made my Outlook crash every time I launched.

    We LOVE SpamBayes and would like support to be added for 64-bit version of Outlook 2010. Our mailboxes have gotten over 12GB and we need all the RAM usage we can get!

    We use Windows 7 x64 Professional

    I have the same problem with Outlook 2010 x32 and Win7 x64. "SpamBayes can not get registred". Changing DEP and access right for the SpamBayes folder did not work. Very sorry, we love SpamBayes too.

    I had the same problem with Outlook 2007 on a 32-but Win7 machine. OL started crashing and the only way to get it to run was to start up with Spambayes disabled. But then I couldn't re-enable SpamBayes -- enabling it had no effect. The toolbar wouldn't show up, and when I'd look at my add-ins again SpamBayes was still disabled.. Reboots didn't help, and it was already listed as a DEP exception. I tried uninstalling and reinstalling but that didn't work either -- until I uninstalled, renamed the spambayes program folder, and reinstalled. Now it's working. And fortunately, I didn't lose any of my settings or spam database.

    I am in the same boat as everyone. I am running Outlook 2010 x64 and Win 7 x 64. When I install SB nothing happens. I am not even getting it to appear in the add in window at all. I have tried reinstalling it several times but nothing happens.

    The SB help section says that if Outlook does not show it in the add-in area to do this: If the SpamBayes addin is not listed, then SpamBayes should be reinstalled (Note that running regsvr32.exe outlook_addin.dll or bin\outlook_addin_register.exe from the SpamBayes directory may also solve this problem).

    I just wanted to report that the first file (regsvr32.exe) does not even exist on my computer anywhere, not to mention in the Spam Bayes directory. And I tried clicking on the 2nd one a few times and nothing happens at all.

    I am with everyone else. I love spam bayes and really don't want to try another spam filter. this is the best one out there. But something needs to be done to make this work with Outlook 2010 x 64. I hope to see an update soon.

    My new install of SpamBayes v1.1a6 fails to load at all in MS Outlook 2010 v14.5128.5000 (64-bit) from MS Office Professional Plus 2010, running on Win v 64-bit.

    Please try installing SpamBayes in a non-default location such as C:\SpamBayes.

    Hello Scott,
    please note the new comment on http://spambayes.sourceforge.net/

    Outlook 2010 Windows 7 1.1a6 1.1a6
    A number of people have reported that SpamBayes will not work on Windows 7
    unless you install it in a non-default location. Installing in C:\SpamBayes
    should do the trick.

    My Spambayes is running with W7, Outlook 2010 - great!
