I'm trying to run a conversion from ESXi to Hyper-V 2008 R2 and seem to have run into a problem. The conversion wizard process runs ok to the end but after clicking finish I get the error

"Failed to convert virtual machine <machine name>. Failed to convert virtual hard disks: Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified"

The last couple of entries from the log file are below. Any pointers on resolving this would be appreciated..
