Entry point not found while creating msix package using MSIX Packaging tool
Hello,
I am a beginner and I am trying to use MSIX Packagin tool. So I started with creating a msix package for 7zip. I downloaded the exe from https://www.7-zip.org/download.html, and specified the location in select installer. I am using self-signed certificate. When the installation completes, it moves to First Launch tasks step and there it does not show any entry point for the specified installer. When I try to browser dialog displays message - we did not detect any new entry points. Run your installer and try again. If I continue to creating package, generated MSIX package is only 19KB in size.
Why entry point is not showing?
Thanks in advance,
Hi krathore
If the tool is not showing the entry point that means it did not detect the executable file being created while it monitored the installer. This can happen if the application you are packaging (7zip) is already installed in the machine before you create the package with the MSIX Packaging Tool. We recommend you package your applications in a clean machine or VM to prevent that.
If the application is already installed before packaging, the package you create will probably be almost empty. You could confirm this by opening it with the Package editor available in the tool and exploring the files in it.
Although I don't think any of these is the case here, the entry point may also not be found if the installer fails (so the executable file is not created), if there is no shortcut created to it (it would show up in the browse dialog to add it), or if you are installing to a different disk drive than the specified install location.

krathore you can specify the entry point in the appxmanifest.xml file and invoke the tool like
makeappx.exe pack /v /o /f mapping.map /m Appxmanifest.xml /p ./abc.msix
Sigmarssonthanks for your reply. To use makeappx.exe tool I would need to create AppxManifest.xml file. So I tried following this link https://docs.microsoft.com/en-us/windows/msix/desktop/desktop-to-uwp-manual-conversion to create xml file. So before packaging I tried to test the application. I ran the add-appxpackage command but its giving following error:
PS C:\WINDOWS\system32> Add-AppxPackage -Register E:\AppxManifest.xml
Add-AppxPackage : Deployment failed with HRESULT: 0x80080204, The Appx package's manifest is invalid.
