All,

I am using Advanced Installer Professional (just updated to 21.3 before this issue) and registered two files in my MSIX package. It installed fine, I tested it, and uninstalled it.

I built a different version of the same MSXI app and continuously get the error:

App installation failed with error message: An internal error occurred with error 0x800703FA. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x800703fa)

It happens when I attempt to install the MSIX package after an Advanced Installer build.

Opening the event viewer to get more details, I get:

ErrorText Package could not be registered.
ErrorCode 0x80073cf6

Another Error on the same attempted install is:

ErrorCode 0x800703fa
ErrorMessage Illegal operation attempted on a registry key that has been marked for deletion.
CategoryName windows.stateExtension

This is confusing and just started after I registered several files in my previous build. I registered a *.exe and a *.dll during the build that seems to have caused the problems. Registered them using the native registation.

Any suggestions how to fix this? I tried a CCCleaner Registry clean but did not work.

Thanks.

Hello Steve,

The error you're encountering seems to be quite general.

Here's what I found at a first glance:

Windows installer service has stoped..

Could you please have a look over that and let me know if it helps?

Additionally, I am assuming this is not happening on a clean machine, right?

Best regards,
Catalin
