Since you have already attempted to solve your problem, some of these suggestions will be repeats. Wade through them and try anything new first. Then, you can attempt to retry some of the others since they might actually work the second time around. The solutions vary in their efficiency sometimes according to whether you are using a 32 or 64 bit version of Windows Vista.
What Does Error 80073712 Mean?
If error 80073712 occurs when attempting to install an update for Windows Vista, the component store is most likely corrupt and in need of repair. What happens is that certain types of data (file, registry, and memory) have become inconsistent or corrupt. This prevents Windows updates from reaching completion.
Use System Update Readiness Tool
In order to fix an error 8007312 related problem, you need to use the “System Update Readiness Tool.” It is essential that you understand two important facts here. First, once you download the “System Update Readiness Tool,” it needs to run a scan. Second, the scan takes at least fifteen minutes (sometimes a great deal more) and it “pauses” somewhere around the 60% completion mark. Whatever you do, exercise patience and allow it to complete no matter how long it takes. This scenario will vary from one computer to another depending on system resources, hardware, software, and the extent of the damage. Visit Support Microsoft 947821 to download the “System Update Readiness Tool,” and to learn more about it. Scroll to the bottom of the page to find the download for your version of Vista.
Downloading Windows Vista Service Packs
Windows highly recommends that computer users download service packs using “Windows Updates.” This practice uses less resources than going through Microsoft’s Download Center. If you don’t have a lot of available resources on your computer and you are trying to download from Microsoft’s Download Center, you can run into problems. Additionally, if you go through “Windows Updates,” it checks automatically for problematic drivers. If they exist, the update will not take place until the drivers have been updated.
Free Support for Problems Installing “Windows Updates”
Microsoft is offering free technical support to anyone experiencing problems installing Windows Vista SP1. This free help is only available until March 18, 2009, so I suggest trying to take advantage of it as soon as possible. You can access this help at Vista SP1 Help. You have three options: email support, individual chat support, and phone support.
