Case

Running the integration tool on a Hyper-V VM with the Hyper-V VSS provider installed may lead to unexpected issues when the Hyper-V provider is also present in the ESXi VM. 

Workaround

1) Run the following command to check the provider ID.
> vssadmin list providers

Provider name: ‘Hyper-V IC Software Shadow Copy Provider’
Provider type: Software
Provider Id: {74600e39-7dc5-4567-a03b-f091d6c7b092}
Version: 1.0.0.0

If the provider ID matches the one in the VSS error content, delete the Hyper-V provider.

2) Delete the following key by Regedit.

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesVSSProviders{74600e39-7dc5-4567-a03b-f091d6c7b092}
