Hello,
I am having the same issue:
App installation failed with error message: Deployment Add operation with target volume 😄 on Package SerifEuropeLtd.AffinityPublisher2_2.0.0.1640_x64__3cqzy0nppv2rt from: (affinity-publisher-2.0.0.msix) failed with error 0x8007000D. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x8007000d)
System info:
Windows 10 Home ver 22H2
64 bit OS, x64-base processor
I just signed up/downloaded the trial version on Christmas weekend. Affinity Designer and Photo have been installed with no issues. Tried installing 3 times and got the same result each time at about 40% completion.
