Invalid View State in IE11 Only

I was wondering if anyone has experienced this issue?  I am receiving an invalid view state asp.net error in the log when I try to log into the site. This is only happening in IE11 as far as I can tell. I have a test machine that is running an older version of IE and I can log in there as well as Chrome. I have ensured I have a unique machine key, adjusted the httpRuntime maxRequestLength, cleared cookies and restarted the browser, accepted all cookies, adjusted the maxurllength, and restarted the IIS app pool. 

Any help would be greatly appreciated. Thanks in advance.

Re: Invalid View State in IE11 Only

yes, it is a well known issue. It means your web server does not have all the windows updates, this was fixed long ago in a windows update.

Re: Invalid View State in IE11 Only

Thank you.

I tired to install this update but, it didn't work. Do you happen to know what update that was?
