Hello,

I mistakenly tried installing the qubes-windows-tools in a fresh windows 7 vm, 
and while most things seemed to work, I must have done something to break 
something to do with qrexec rpc calls.

Most inter-vm communication fails with some kind of request refused error. For 
example, I cannot use qvm-copy or qvm-copy-to-vm. Another error is when I'm 
trying to update Dom0. Packages are downloaded, but before trying to install 
them, I receive the following error:

'/usr/lib/qubes/qrexec-client-vm dom0 qubes.ReceiveUpdates 
/usr/lib/qubes/qfile-agent /var/lib/qubes/dom0-updates/packages/*.rpm' failed 
with exit code 126!

I'm not really sure where else to look for proper logs, so please let me know, 
I'd be happy to provide them regardless of if this is something I can fix. 
Right now I've resorted to backing up my qubes to sys-usb, since the backup 
utility in Qube Manager does not recognize any other VMs. I'm sure this is 
something to do with the changed in qrexec in 4.1 from 4.0, but don't have 
quite enough of an understanding to say what exactly.

Also, while backing up, I see I have the option to backup Dom0, but is this 
advised in this situation? I do have some files I'd like to backup there, and 
since I can't send them to another qube, I'm not really sure how else to go 
about backing them up .. either way I'll figure it out since they are mainly 
just scripts I've written in the past few days, but it'd be nice to find a way 
to save them somewhere if I do need to reinstall to fix this issue.

Please let me know where to start/look for a fix if you understand what the 
issue is a bit more than myself.

Thanks in advance..
