[Vol-users] Having Trouble Running Vol

Hello, I am not sure why I am having trouble running vol against a Win7 memory image: I ran the imageinfo plugin against the image and it suggests: Win2008R2SP0x64, Win7SP1x64, Win7SP0x64, Win2008R2SP1x64: But when I select Win7S1x64 profile for other plugins I get following error: Any suggestions on what I am missing? Thanks in advance.
