new member: Register Hello All,microsoft office 2010 Home And Business x64, I've set up Neighborhood CA (Microsoft) . With the time of set up,office Home And Student 2010 activation, it absolutely was operating great. Abruptly once one week,microsoft office Home And Student 2010 64bit, CA service is stopped and when tried to start the services it displays the error : "KeySet does not Exists 0x80090016(-2146893802)". I checked the Event Viewer also. In Event Viewer Error is as follows: Source :certsvc Event Id :100 Explanation : Certificate service did not launch: could not load or verify the current CA certificate. <CA Name> Keyset does not exists 0x80090016(-2146893802). Currently I've reinstalled the CA and now it is doing work good again. Can anyone help me in this regard? what can be the reason? I have not done any changes. Regards,microsoft office 2010 Home And Student 64bit, Anu
