Question: I m running windows vista home premium
recently When I start the system I receive an error message stating Runtime Error '339'
Component 'MSCOMCTL.OCX' or one of its dependancies is not correctly registered: a file is missing or invalid.
Most of the programs when I try to run I receive the same error message.
I have downloaded the recent mscomctl.ocx file from microsoft, copied it to C:\windows\system32 and have registered it through regsvr32. But still the problem persist. Many of the programs are not opening stating this error
Please help

This can happen if you have deactivated User Account Control under windows Vista. To reactivate it, Click on the "Start" Menu, then open "Control Panel". In the Control Panel, select "User Accounts and Family Safety". Click on "User Accounts", and then click on "Turn User Account Control on or off". Clear the tick mark on the box beside "use User Account Control (UAC) to help protect your computer", then validate with the "OK" button. When prompted, choose to restart the computer for the changes to take effect. The changes will affect all users on your computer.
