install specific windows update after VC++ 2005?

[phil_d_b]

Hi there;

I have an installer that checks for the existence of VC++ 2005 SP1 and installs it if needed etc etc. Unfortunately, I ALSO need it to check for and install a certain Windows Update http://support.microsoft.com/kb/2538242

Is this possible? Can I have my installer do the following:

1) Check for and install VC++ 2005 (I've got this part working already.)
THEN:
2) install Windows Update KB2538242


Any advice is appreciated!

Check registery key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\KB2538242

Ok that helps me establish if the windows update has already been installed but how do I proceed to install it if I find that it is needed?

Ok I have created a custom prerequisite and it seems to be doing the trick.
