Specify the exact product & version of Acronis that you are using. Also specify the product & version of VMware that you are using. If you are using VMware Converter standalone version 3.0.3 you can import Acronis images (.tib) created with:
1. Acronis True Image 10. (This is found under their "Home products")
2. Acronis True Image Echo 9.1 (This is found under their "Small Business products")
As you will notice the current versions of these Acronis products are 11 and 9.5 respectively. These are currently not supported by VMware converter. It might be possible to convert these tibs to VMDK using Acronis products and you will have to reference the Acronis product manual for that.
As for the "steps" involved to getting a "tib" to a VM, it is fairly straight forward using Converter. You need to perform an "import" operation and select .tib as your source. Look at page 35 of the Converter manual http://www.vmware.com/pdf/VMware_Converter_manual303.pdf
