Draftsight 2026 SP1 Windows installer issue

Hello,

I am a Draftsight user trying to add a new subscription license to a virtual machine. 

When trying to install latest installer I get a message error stating that installation cannot be completed (error code 255), same is obtained if installation is made for Draftsight 2026 SP0. Any suggestion on how to correctly install latest software release?

 

Thank you in advance!
