Windows 7 64 bit SP1 error 0X80070490

Hi All, from what I have been reading this topic has been discussed for the past three years and for the past two weeks I have worked my way through many Forum's including this one, but I am still unable to update my Windows 7 with SP1. I have only had this laptop for about three months but I cannot get it to load SP1.

The update runs to completion but when my laptop restarts I am unable to install SP1 due to error 0 X 80070490. It says update unsuccessful reverting blah blah.

I have checked the Acer site and all drivers are up to date, I have tried the Windows update many times, I have downloaded the SP1 as a file and tried that and I have tried both methods in Safe Mode. I have no language packs loaded except English so I couldn't try the language pack remedy mentioned in other Forum's.

Can anyone else suggest that something else that I try or is a system repair for Windows 7 my only hope, I didn't want to do that except as a last resort. A lot of stuff I am reading is from 2011, is there anything lately which cracks this problem, I cannot believe it has been a pain for so long without a fix, from MS.

I have also tried Checksur and the Microsoft Fixit, but nothing will clear this error, all other updates apply correctly.

anyone have any good ideas, or any other ideas? I'm getting desparate.

regards,

kenshep

Windows 7 SP1 error 0X80070490

 

This is how I fixed it a couple of time--it was a pain.

As described here, download and install the system readyness tool
You receive a "0x80070490" error code when you use Windows Update or Microsoft Update Web sites to install updates

Running it didn't fix it for me. However, upon reading the log created by the tool (checksur.log in C:\Windows\Logs\CBS) it specified which files were corrupt. The corrupt files were different in each case. In some cases, I copied the files from a different machine, in some cases, there were multiple copies of the file and I took one from an unreferenced directory and replaced the one identified as bad.

After that, I reran update and it applied.

 

Hi gerryf19, thank for your reply it was the only thing that I didn't try and it still won't take. The error that shows up in the log is a Language Pack error but as I only have the English LP loaded I am at a loss as to what to do. Most other solutions involve uninstalling all the other LP's except the one you are using. Is there anything else I could try or should I ask Microsoft? Thanks for your help.

 

not sure... could you post the relevent section of the log?
