Trend Micro 2012 initializing error

Hello everyone,
I have recently purchased a laptop. A friend of mine suggested me to install trend micro internet security. I installed this software successfully and the installation was fully completed. When I started my laptop, the trend micro did not start. It appeared on my toolbar for a fraction of a second and then it faded away. The following error message popped up on the screen after that:
"Trend Micro Titanium Internet Security 2012
Installation Incomplete
A problem prevented the installer from completely setting up Trend Micro Titanium
Internet Security 2012. No changes have been made to your computer.
Please close any other programs currently open before restarting the installer.
If following this advice does not solve the problem, you can also get more help
online. (Error code:#1603,0,0×000)"
Can anybody explains why do I get this error and what does it mean?
I tried to resolve it but I failed. If anyone can be of some help in resolving my problem, I'll be highly grateful.
Waiting for your replies
Regards
Grace
