ERROR_INSTALL_TRANSFORM_REJECTED

ERROR_INSTALL_TRANSFORM_REJECTED means one or more MSI customizations were not allowed by software restriction policy. The package may be valid, while the applied transform is blocked.

Verify the exact .mst file and deployment policy used for the failed installation rather than retesting only the base MSI.

What to check

  • Check the installation command line and deployment configuration for every transform that is being applied.
  • Verify that the transform belongs to the intended MSI version and comes from an approved source.
  • Review the applicable software-restriction or application-control policy with the administrator responsible for it.
