Hi,

I am performing an upgrade of EPiServer from 6.1.379.0 to version 7.0.859.1.

However, soon after I run the installer I get the following error:

An error has occured and the transaction will be rolled back
Rolledback

An unhandled error has occured:

Does anybody know what I can do to fix this?
