Last update: 13-04-2022


  • You try to register a license
  • License registration fails with the error "Failed to register License: Signed data is invalid"


A mismatch in the type of license used. There are 2 different types of licenses which are incompatible with each other. 


1. Check what type of license is in the License file:

  • Acronis Cloud Manager license size is about 1Kb.
  • Manager Standard, Cloud Security and V2V licenses are all 268 byte size.

2. Get the right type of License file, which matches the edition of Acronis Cloud Manager you have:

  • Contact your reseller or partner to re-issue the matching type of license file.
