Symptoms
Acronis Disk Director 12.5 is installed on the same machine with a different Acronis product, e.g. Acronis Backup 12.5 or Acronis True Image 2019.
When creating WinPE-based bootable media, it is not possible to select both products to add them to media.
Cause
Product limitation.
Solution
As a workaround, create a separate WinPE media for each product.
