Same error as a previous writer except I have Outlook 2007, Windows Vista and Trend Micro Antivirus w/Webroot Spy Sweeper. I tried the suggestions posted for the other writer but it appears they don't apply to my system.
When I double click the Outlook icon the outline of the window comes up but then goes away in a few seconds and is replaced with the error message.
The problem started right after I tried to sync my Blackberry using the Blackberry Desktop Manager. My computer freezed and I had to manually restart the system, went into safe mode then restarted in regular mode.
I ran Office Diagnostics without success.
During the search for a solution I also recieved an error message: msiexec.exe application error, The application failed to initialize properly (0xc0000142). Don't know if this is related to my problem.
Any suggestions are appreciated.
