Hi,
I'm trying to convert windows 2008 R2 server VM which is in (ESX 3.5) to vSphere 5 (ESXi 5) through vmware "converter standalone client"
The Windows VSS components are more than likely failing on the Windows side and thus causing Converter to fail. Converter uses the VSS components to take a snapshot.
If you look in the Windows Event logs you will probably some events being logged in relation to VSS.
You should read VMware Knowledge Base article http://kb.vmware.com/kb/1019690
Hope that helps.
I know this is a really old post; however, I still ran into this issue many years later and have found a solution. I was converting a 32 bit Windows 7 machine that was already a VM - I simply wanted to reduce the system volume's size. It was too big and was making cloning take longer than it should.
The solution that worked for me is not my work. I take no credit for it, nor do I take any responsibility for what it does. I blindly followed these instructions and it worked perfectly for me. I will provide a link to the original web site AND a copy of the instructions in case that website no longer exists one day.
I only followed these steps thru part 6. I did not need to go any further after that.
Good Luck. Hope this helps someone as it helped me.

Below here is the information copied directly from the website I just listed above.
This article details how to troubleshoot VSS errors.
Backups may be failing due to Microsoft's VSS framework being in a bad state. This could be caused by clashes between ShadowProtect and other programs trying to use VSS at the same time. Only one writer can use VSS at any given time (See article on "Understanding VSS and ShadowProtect"). Another possible cause for VSS errors is that the necessary system services may have been mistakenly disabled.
If Microsoft's VSS framework and/or some of the VSS writers are in a bad state, you need to clean the system up before your backups will work.
Part 1:
Part 2:Go to Start | Run and enter "services.msc" - Click OK.
Part 3:Next, you need to delete all greyed-out devices (non-present "Storage Volume shadow copies" devices) possibly left over from previous snapshots.
These can only be removed one at a time. Select one from the list, right click, and then choose uninstall. Repeat this process until all greyed-out devices are removed. If there are devices still listed which are not greyed-out then the vssadmin delete shadows /all did not work properly. Try running it again.Part 4:Do not delete any of the Storage Volumes.Part 5:
Part 6:Reboot.Part 7:After you finish rebooting:
ConclusionFollowing the steps listed above should clean the system up enough for you to start using ShadowProtect. Proper VSS interaction is very complex and many backup products leave various components (especially VSS writers) in bad states. This can cause problems for other backup products. If you are using any other backup products, it's very likely that they will corrupt the states of various VSS components. You must always ensure that ShadowProtect does not run at the same time as other backup software such as Backup Exec, Acronis, etc.
