Configuration: Windows 7 Home Premium (64-bit) Outlook 2010 SpamBayes 1.1a6 Starting from a clean system (no SpamBayes files or directories) and with Outlook not running, I install SpamBayes. It installs fine. I start Outlook, and get the SpamBayes add-on startup wizard (where it asks me about locations for good and bad messages, where to put questionable messages, etc.). SpamBayes initializes properly: I see it in the COM Add-ins list of Outlook, I see the SpamBayes toolbar, I can access the SpamBayes manager. I stop Outlook. I start Outlook. SpamBayes does not initialize. Instead I get a SpamBayes pop-up saying "There was an error initializing the SpamBayes addin. Please re-start Outlook and try again.". Restarting Outlook does not help - I get the same pop-up. Outlook still has SpamBayes listed as an active COM Add-in. There is no SpamBayes error or log file generated. Uninstalling and re-installing SpamBayes does not fix the problem. When I do this, the very first time I start Outlook, I get the SpamBayes pop-up. After some experimenting, I believe the problem is with the SpamBayes database files (default_bayes_database.db and default_message_database.db): 1. These files are not deleted when I uninstall SpamBayes. On installation, they are not overwritten, but remain unchanged. 2. If I stop Outlook and manually delete these two files, when I start Outlook, SpamBayes initializes fine (I get the SpamBayes add-on startup wizard). These files are located in "c:/users/<user id>/appdata/roaming/spambayes". I can't see any problems with these files or the directory: Everybody has read/write/modify/execute permissions on everything. Anybody have any suggestions I can try, or some more information I can supply? Douglas Whitten dewhitten@comcast.net
