Updating Acronis Backup and Recovery 10 to the latest build 11639 causes installation failure.

When trying to update to build 11639, installation fails if ABR components were installed for single user.
Installation fails with a similar message:
Code: 06442537Line tag: 0x39435106l5f8e4badlMessage: Installation error.SuberrorCode: 01603Line tag: 0xbd28fdbdl64edb8bclMessage: Fatal error during installation From MSI log:1: MSIGEN:The following products will not be removed automatically because they were installed on a per-user basis (the products are available for only one user of this machine).

Solution:
There are two possible workarounds:
1. Extract the components that fail and install them through command prompt by issuing the following command:
msiexec.exe /i PackageName.msi ALLUSERS="1" ADDLOCAL=ALL
2. Uninstall the failing components and then install them from the installation package of the new build:
* Uninstall all of the listed components that were installed in the system from Control Panel:
Windows 2000/XP/2003: Control Panel -> Add or Remove Programs
Windows Vista/7/2008: Control Panel -> Programs and Features
The components to uninstall are:
Acronis Backup & Recovery 10 Bootable Media Builder
Acronis Backup & Recovery 10 Management Console
Acronis Backup & Recovery 10 Agent for ESX/ESXi Virtual Appliance
Acronis Backup & Recovery 10 Wake-on-LAN Proxy
(!) This will not affect the already configured/scheduled backup plans.
Launch installation of Acronis Backup & Recovery 10 Build 11639. Choose Modify and check the components that have been uninstalled in the previous step.
The installation of the update should be successful.
