Can not Sign the MSIX pacakge with self-signed certificate
I used Makeappx tool to convert my appx package to the msix package and now I want to test my msix package. I created a self-signed certificate by following the steps from https://docs.microsoft.com/...
I have the same issue with self-signed certificate (0x80070032). The name is valid, and I can use the cert to sign an exe without issue. I am using 17134 version of signtool, and have tried both the x86 and x64 version of signtool.
Event operational log generates a single information entry (Event 181 - The reader was created successfully without manifest validation).
Enabling debug log produced single event of Event 0 (ErrorCode 15003 with EventPayload of all zeros))
TIMOTHY_MANGAN and Stephen Morgan, looks like you are using the RS4 version of signtool. Please use the latest from the insider preview SDK:
