There is no need to uninstall the existing version of your copy of an Acronis product before updating it to the latest build
The latest update of an Acronis product can be installed over the existing version of the same product. It can also be installed from scratch on a clean system.
Any update of any Acronis software is a full product.
Installing the latest version or build of an Acronis product over the existing version reinstalls Acronis drivers in the system. Depending on how major the update is, this operation may or may not require the system reboot.
Installation over an existing version will not ask for a serial number.

After updating, it is also recommended to recreate Acronis Bootable Media to have better hardware support.
(!) Acronis does not guarantee that images (backup archives) created with a newer build of the product will be supported by older builds. This means that restoring an image created with Acronis True Image Build 8163 may fail with Acronis True Image Build 8076.
