Application Error - DLACTRLW.EXE

My newly bought Laptop was running very slow even at startup. After I installed MS Office, I tried to clean the pc by running CleanUp! After that, my worst problem started. I couldn't get the machine going. I forced to do the hard restart. "DLACTRLW.EXE - Application Error, the application failed to initialize properly (Oxc0150002)…." this is the Error that I have got. The "Start" button was went missing. I tried to re-install the Windows XP pro SP2, but it ended with a Stop Message: Technical Info: Ox0000007B (OXF7AF4524, OXC0000034, Ox00000000, Ox00000000) When I tried to install some program like TuneUp Utility, an error returned saying that the application failed to start due to incorrect configuration….. so, i couldn't install any software at the moment, what should I do??? Sorry to say that i am new in this forum. I don't really know where to post this thread. I really need all your guidance and help. Warm regards.

Just because a machine is "newly bought" doesn't necessarily mean that it is "new", or that the Operating System is fully patched and updated.

Head over to Microsoft and allow to scan for updates.
Let us know if the problem persists.

You may also benefit from examining your StartUp List.
GoTo: Start - Run - (type) MSCONFIG
Click on StartUp (tab)

scan throught the list of programs and functions that activate at boot.

You can check up on various routines to determine if they are necessary, optional, safe to disable, etc. , here:

Dough, Thanks for your reply. The windows was updated before it crashes. I can't run MSCONFIG because the "start" button does not appear. Regards.
