I have confirmed that using 32bit qemu-ga.exe on 64bit Windows causes exactly what you explained at the previous e-mail. (And maybe the hung is caused by a dialog box popped up *behind* the terminal.... I think this is because the box belongs to a Windows service, but I don't know how to avoid it...) Could you tell me which arch (32bit/64bit) of Windows and mingw (mingw32-* or mingw64-* in Fedora package) are you using?

I noticed afterward that I'd already had the service running, so figured that that might've been the problem. So I stopped the service and unregistered it (using a qemu-ga install that was in a separate directory). Then I went back to install via qemu-ga.exe -s install, and it just hangs with no output. I wasn't sure how to reset the state, so I took the Windows approach and rebooted. After reboot, running qemu-ga -s install gives me: C:\Users\mdroth\Documents\qga>qemu-ga.exe -s install Registering QEMU Guest Agent VSS Provider: C:\Users\mdroth\Documents\qga\qga-vss.dll C:\Users\mdroth\Documents\qga\qga-vss.tlb Failed to pCatalog->InstallComponent.

(Error: 80040154) Class not registered Removing COM+ Application: QEMU Guest Agent VSS Provider Removing COM+ Application: QEMU Guest Agent VSS Provider [mdroth@vm5 ~]$ I'm not sure if I'm still in a bad state from earlier, but I can't seem to recover from here. If I try running qemu-ga -s uninstall, then qemu-ga -s install again, I get a pop-up error saying: "CoCreateInstance(VSSCoordinator) failed. (Error: 80040154) Class not registered Any ideas what's going on here? I'm on a Windows 7 vm and built using a Fedora 18 mingw environment. Let me know if you need any additional information to debug.
