Hi,

I am trying to upgrade a site from 5.4.2 to 5.6.5 (CE), and then to 6.1.1.

Following the wiki recommendations I have copied the site to a new site in IIS (6.0 FW 2.0.50727) . The site works fine.

However, when I copy the 5.6 upgrade files to the site and the call /install/install.aspx?mode=upgrade, My browser (Chrome) eventually times out with the "Error 100 (net::ERR_CONNECTION_CLOSED): The server closed the connection unexpectedly"

The following event is logged in the Application event log. There is no error in the DNN event log:

Has anybody else come across this problem and any suggested workarounds?
