Hi Jill, Sounds like you are running Vista. appwiz.cpl can actually be typed into the Search box in Vista, but in fact simply brings up the "Add/Remove Programs" dialog. Goodness knows why they couldn't have simply said to run that in the first place?? BTW, in Vista, RUN is in Programs: Accessories. George.

Thanks for the link, but I'm slightly confused. It says on the page to click start, then click run. I can't find run in my start menu. Should it be there, or does it mean that I type the word run in the search box? Thanks. ----- Original Message ----- From: George Bell <mailto:george@xxxxxxxxxxxxxxxxxxx> To: access-uk@xxxxxxxxxxxxx Sent: Monday, April 20, 2009 10:18 AM Subject: [access-uk] Re: problem with windows defender Hi Jill, It's a known problem, but there is a Microsoft Knowledge Base article on it.. http://support.microsoft.com/kb/931849 George.

J 10 with latest update, W V Premium. I've had this problem for a long time now, and wonder if anyone has any ideas on how I can fix it. I ran a full system scan with Defender and no problems were reported. Since then, each time I switch on my comp I get the following message: Application failed to initialize: 0x800106ba. A problem caused this program's service to stop. To start the service, restart your computer or search help and support for how to start the service manually. Then there's an Okay button which I click on to get rid of it. I tried restarting the machine, but to no avail. I also tried starting it through the programs list, but still the same. I've also tried getting windows to search for a solution to fix this problem, but nothing. I have a feeling Defender has become corrupt in some way, but don't know how. any ideas what's gone wrong and how to rectify it please? Thanks. Jill.
