“So far, we’ve been able to determine that this problem only affects a small number of customers in unique circumstances. We are working to identify possible solutions and will make the update available again shortly after we address the issue,” wrote Microsoft product manager Nick White on the Vista blog.
He added that customers who may be experiencing this issue can use system restore to correct it or contact 1-866-PC-Safety for help troubleshooting. Also, he promised that additional guidance would be available via Microsoft’s free Update Support Center.
