Could not complete the operation due to error 80020101 in IE11
My asp.net application was working on all browsers before IE11 came in. But when IE11 launched and users started to use it,I got lot of complaints about the UI mess and postbacks . The most irritating thing was neither AJAX UpdatePanel was working nor any postbacks on the page. So I googled it for almost two days trying different tricks/tips but didn’t work, but then I found this hotfix on microsoft website; http://support.microsoft.com/kb/2836939/en-us.
Most important thing is that after downloading this file you need to install on the server where asp.net website/application is deployed/hosted. Because this error is not an error of your project/application, but its an issue of dotnet framework 4.0 and 2.0.
