Componentes Necesarios Para Instalar Service Pack 1 Windows 7

admin

It’s that time of year again, and as always, when I vis­it the fam­ily over xmas there are vari­ous PC issues to resolve. This year there were blessedly few issues, but there was 1 prob­lem that it took me quite a while to track down and resolve. One of the fam­il­ies PCs was fail­ing to install Win­dows 7 ser­vice pack 1. It’s a fairly new PC and came with an OEM install of Win­dows 7 x64 Home Premi­um, all legit and activ­ated. It also has up-to-date anti-vir­us pro­tec­tion, and oth­er than the SP1 install prob­lems it seemed to be in excel­lent work­ing order.

Error 80073712

Faltan uno o mas componentes necesarios para el service pack windows 7. Hace unos dias esta intentando instalar service pack pero me pone que e. Sigan todos los pasos como se muestra en el video.El archivo es CSDversion.

The error thrown by win­dows update was error 80073712, which accord­ing to win­dows help (and the Microsoft help page) “occurs when the Win­dows com­pon­ent store is cor­rupt”. Microsoft provide a tool, called the Sys­tem Update Read­i­ness tool (KB947821) which it sup­posed to fix this prob­lem. I down­loaded the tool and ran it (which took quite a long time), after which it repor­ted suc­cess. I then reat­temp­ted the SP1 update but it still failed.

After fur­ther research I dis­covered this is an issue which has plagued both 32 and 64 bit ver­sions of Win­dows, ever since Vista. It seems to affect all ser­vice pack releases (KB936330, KB948465 and KB976932) Hence the Sys­tem Update Read­i­ness tool being for Win­dows Vista, 7, 2008 and 2008 R2. There are lots of unhelp­ful sug­ges­tions avail­able, but the actu­al solu­tion is fairly simple, as long as you have access to anoth­er PC with the same OS installed! In my case I had my laptop with me, run­ning Win­dows 7 x64 SP1. I’m not sure if hav­ing SP1 may some­times make a dif­fer­ence, or if hav­ing Pro­fes­sion­al instead of Home Premi­um may like­wise some­times make a dif­fer­ence, but in my case these dif­fer­ences did­n’t mat­ter — my solu­tion worked just fine. For more detailed inform­a­tion, I found the Microsoft Tech­Net art­icle “Advanced guidelines for dia­gnos­ing and fix­ing ser­vi­cing cor­rup­tion” very useful.

The Solution

Firstly, down­load and install the Sys­tem Update Read­i­ness tool. If you’re lucky this will just fix the prob­lem the first time. How­ever, before attempt­ing the ser­vice pack install, we’re going to check…

Click on start and in the search box type “note­pad %windir%logscbschecksur.log” to open the read­i­ness tool’s log file.

At the bot­tom of the file there should be a sum­mary which looks like

If the num­ber of errors fixed is the same as the num­ber found then you should be sor­ted — you can now just go ahead and install the ser­vice pack or win­dows update as nor­mal. How­ever, in my case it was­n’t, so…

The log file iden­ti­fies any files it could­n’t fix. Files it can­’t fix are ones that aren’t present on the sys­tem for some reas­on. You need to get them from anoth­er PC run­ning the same ver­sion of Windows

In the log file, under the sec­tion called “Check­ing Com­pon­ent Store” there will be a list of files that are miss­ing or cor­rupt. I had 4 lis­ted as below…

The mani­fest files can be found (on anoth­er PC) in %windir%winsxsManifests and the folders con­tain­ing the oth­er files are found in %windir%winsxs

Copy the miss­ing files to the PC with the prob­lem, into the fol­low­ing locations

.mani­fest files into %Windir%TempCheckSURwinsxsmanifests
.mum and .cat files into %Windir%TempCheckSURservicingpackages
any files from the folders with the long names (in my case the 2 LDDMCore.ptxml files) go into the appro­pri­ate dir­ect­ory in %windir%winsxs

This final step may require tak­ing own­er­ship and chan­ging the per­mis­sions of the dir­ect­or­ies in question.

Now re-run the Sys­tem Update Read­i­ness tool. Once re-run repeat step 2 to open the log file, and con­firm that the sum­mary sec­tion now says the num­ber of fixes matches the num­ber of problems.

Assum­ing the value for fixes is now equal to the value for prob­lems found, you can now re-run the ser­vice pack or win­dows update, which should succeed.
