[SOLVED] Problem with install_msi_if_needed and msix file

[t.heroult]

Good morning
I want to develop a package for the new MS-TEAMS which is provided as msix.

But when I try a simple install_msi_if_needed('MSTeams-x86.msix') in pyscripter, I get this output:

Code: Select all

2023-11-09 15:13:13,714 CRITICAL Fatal error in install script: MSIError: open failed:

    db = msilib.OpenDatabase(msi_filename, msilib.MSIDBOPEN_READONLY)
_msi.MSIError: open failed

FATAL ERROR : MSIError: open failed

Any idea what's going on?

Hi Thomas,

it seems to me that the msix format has very little to do with the msi format. The msilib library, which is used underlying the install_msi_if_needed function, doesn't apparently handle it.

For now, we'll have to run it with something like run(), I believe...

I understand, but what's inconsistent is that from the console, I launched the new package wizard, the first option offering msi, msix, and exe, and after selecting msix, PyScripter opens with the `install_msi_if_needed` line already created.
This needs to be reviewed if the function can't handle msix files.

So, I don't see how to install MSIX with WAPT.
The simplest way would normally be to use PowerShell with Add-AppxPackage, except that this operation isn't possible with the LOCAL SYSTEM account used by WAPT...

Indeed, I just saw that msix is ​​hardcoded in waptconsole

We're going to remove the reference; it's a historical error

In the meantime, you can try something like this:

Code: Select all

def install():
    filecopyto('MyApp.msix','c:\MyApp.msix')

def session_setup():
    run(r'powershell Add-AppPackage -path "c:\MyApp.msix"')

Hi Simon
, as I mentioned in my previous comment, it's not working.
At least, it works in PyScripter since it's launched with my account, but the WAPT agent runs with the SYSTEM LOCAL account, which doesn't have permission to run "PowerShell Add-AppxPackage". This is forbidden by Windows, and the same applies to Add-AppPackage itself.

[sfonteneau]

But in my example it's a session_setup, so not a system, so it doesn't work either?

[t.heroult]

I don't know what the result would be in session_setup...
I'll test it and see.

More later!

Negative feedback, nothing happens.
The command used is: powershell Add-AppPackage -Path "C:\Software\bin\MSTeams-x64.msix"
Launched by session_setup: nothing happens
Launched from a PowerShell window (standard user): it works...

Code: Select all

def session_setup():
    cmd = 'powershell Add-AppPackage -Path "C:\Logiciels\bin\MSTeams-x64.msix"'
    run(cmd)

[sfonteneau]

Hmm, the 'r' before the string?

Or should I just use the full path:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
