Solution

  • We solved this issue. There were two things that we were doing wrongly.

    1. Sitecore update installation wizard had some issue with Mozilla Firefox. The frame in the picture that says 'The connection was reset' is an iframe that keeps getting updated with the actions that were performed. If it does not get updated for a while then Firefox closes the connection. So the solution is to use a supported version of Internet Explorer.
    2. The reason why it was stuck at process 1936 and not updating the iframe content was because sitecore was trying to update some files and it did not had privileges required to update it. So the solution is to give IIS worker process access to data and website folders. To do that select website folder -> right click -> properties -> security tab -> Edit -> Add -> Type IIS_WPG -> Check names -> Ok -> Then give full control to the IIS_WPG user -> Ok. Do the same to data folder and restart the installation.
