ABR10 installation finished with warning (Acronis VSS Provider)

Thread needs solution

ABR10 installation finished with warning:
Acronis VSS Provider is not installed. Microsoft Software Shadow Copy provider will be used instead.

I'm trying to install ABR 10 Advanced (build 13762) into virtual mashines running Windows 2008 R2 SP1. My hypervisor is Windows 2008 R2 SP1 Enterprise.

ABR 11 (build 17440) installation on virtual machine with 2008 r2 sp1 finished without warning
In Windows event log I see, what Acronis VSS provider successfully installed

Is ABR10 compatible with 2008 R2 SP1 guest virtual machines?

Same issue on test phisical computer with fresh Windows 2008 R2 SP1 installation from DVD. No additional software, no updates from Windows Update. Configuration changes - only set time zone and computer name.

I have acronis_vss_47891,91.log with error codes in the %temp%:

On another server with Windows 2003 SP2, where ABR10 was installed successfully, I found acronis_vss_39218,58.log
Acroins VSS provider was installed, but error 429 was present. Therefore, it's not a real problem.
On 2008 R2 - vbs script can't

Hi katbert,

Thank you for your posting! There was a known issue in ABR10 with the installation of Acronis VSS Provider on the Win2k8 R2 systems. This issue was fixed starting with the version 11. So if you have the installation file of Acronis Backup & Recovery 11, I would suggest using this version. Otherwise you can safely use native Microsoft System Provider. For more information please refer to the following topic.

Thank you!
