I just updated Photoshop (v26.11), Dreamweaver (v21.6), Media Encoder (v25.5), and Premier Pro (v25.5). Now, when I open either Photoshop or Dreamweaver, the application opens, then immediately closes. Hosts file is up to date, and blocking Internet access (in, out, or both) has no effect. I'd appreciate any help in resolving this.
I also observed that Media Encoder and Premier Pro both threw the "Unlicensed Application" complaint after updating, but blocking Internet outbound solved that issue.
Never mind. I finally found it.
