Question : VmWare on Win7 x64 - Failed to take snapshot of source volume

Hi.

I cannot convert my Win7x64 work environment to VM using the VmWare Workstation 7.1. :-(
All the time it reports errors like - "Vsnap does not have admin rights", "Failed to take snapshot of source volume" and blah-blah. Please see a piece of a log file enclosed.
I have browsed lot of resources, tried different options but all of them do not work. :-(

Also I have following message in system events:

Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {e579ab5f-1cc4-44b4-bed9-de0991ff0623} and Name IVssCoordinatorEx2 is [0x80040154, Class not registered
]. Operation: Instantiating VSS server

Thus, it looks like something wrong with Volume Shadow Copy Service but I do not see what exactly is wrong and how to fix it?!

I have checked all the services required by VmWare are running, typed a commands:
net start ufad-ws60
net start "tcp/ip netbios helper"
net start swprv
net start vss
And then checked in services.msc that they are really running.

Also a detail: the VmWare convertion wizard started fine, I specified all parameters and clicked [Finish] to start converting process. It created a target VM, wrote a message "Taking a snapshot of the volume" and immediately fail. Here are the messages it shows in a GUI:
===begin===
11:36 Step 1: Connecting to VMware Converter Agent on localhost
11:36 Step 2: Creating target virtual machine and converting data
11:36 Configuring parameters for the target virtual machine...
11:36 Creating target virtual machine...
11:36 Taking a snapshot of the volume...
11:36 ERROR: Failed to take snapshot of a source volume.
Possible causes include not having any NTFS volumes on Windows XP or Windows 2003 source systems, and not having enough free disk space.
===end===

So, question is - how to make it working?!
How to convert my Win7x64 work computer to VM using a VmWare Workstation 7.1?
Is it possible at all?!

Regards,
Dmitry.

Answer : VmWare on Win7 x64 - Failed to take snapshot of source volume

Hi "Dmitry"...here is a somewhat recent post on a similar error during conversion. There are MS KB's referenced that may provide the assistance you're needing. I assume you're converting using the converter within Workstation? It may not matter what tool you use (I want to suggest downloading the free Standalone tool from VMware's site) because of the VSS error. If that doesn't work, try to resolve the VSS errors from the MS KBs referenced in the URL:
http://www.experts-exchange.com/Software/VMWare/Q_26197114.html?sfQueryTermInfo=1+10+30+convers+dure+error+vss

If all else fails, you can download a trial of Acronis True image, image your box, then convert it using Converter.
