[wix-users] : Error 0x80070002: Failed while prompting for source

[Nick Elmer]

Hi All,
Looking for some assistance with an install issue. I am updating a package from Wix 3.8 to 3.11. The package used to expect dependent MSI's to exist on the disk. However, with the changes in Wix 3.10 and beyond, that obviously doesn't work any longer. So, I decided to embed the dependent MSI's inside the installer. However, now when I execute, I get the errors below. Searching the web there are many who renamed their installer. My installer is not being renamed, so that is not my issue. Other references were to use insignia to sign. I fixed that as well.

Looking for some assistance to help me resolve the issue. Thanks in advance!
