While trying to install Sims 2, I received a message saying I needed to upgrade my Directx 9.0 to 9.0c. I went into the Microsoft website and downloaded the 9.0c, but when it was going to finalize, an error message came up saying "cabinet file necessary to install file cannot be trusted". I've gone through the game manufacturer, Microsoft and Dell (my computer manufacturer) and noone seems to be able to figure it out. I would appreciate it if someone could help me install directx 9.0c. Thanks so much!

Thanks for your quick reply. I tried everything in the order that you posted, but it is still giving me that error message! Any other ideas? Sorry!

You can use this guide to repair XP

Possibly, you will need to press the start button and keep tapping the delete key, (possibly F2) until the PC enters set up. Change the boot order to CD ROM Drive then hard drive, press F10 then press enter, load the XP CD then type Y then press enter, as it reboots, look for press any key to load from CD, press enter

You will need the XP product key to complete this

If you have audio / video files which are subject to DRM you should check with the provider for known issues with performing an XP repair install
