Microsoft has admitted that patches for critical software bugs made available on its download page on Tuesday would not install because they were corrupted.
The software giant had warned users to update their Windows operating systems following the disclosure of three critical software flaws affecting Internet Explorer and Windows, which could let hackers take control of affected systems.
But users trying to get the patches from Microsoft’s download site in the first few hours after their release found that the update would not install.
During publication of the patches to Microsoft’s download centre, “a corruption occurred in one of the final stages of publication that affected the updates”, a company spokesman confirmed.
Patches made available via Windows Update, Microsoft Update and the Windows catalogue were unaffected by the problem.
“We immediately pulled the ability to get the updates from the download centre, investigated the cause of the problem, and re-published the updates,” the spokesman said. “The updates are now available on the download centre and we have re-released the bulletin to notify customers.”
