Hi Martin,

I'm experiencing an issue with the Microsoft Store version of WinSCP.

I initially tried to update WinSCP several times through the Microsoft Store, but the update repeatedly failed. The Microsoft Store displayed the following message:

"Something happened. We're aware of the problem and we're working to fix it. Try again later."

Error code:

0x80073CF6

The package identified in the error is:

9P0PQ8B65N8X-MartinPikryl.WinSCP

After restarting Windows, the update was eventually installed successfully. However, after the update, WinSCP stopped launching.

I tried launching WinSCP from the Start menu and also by clicking Open directly in the Microsoft Store, but nothing happened.

I then tried the Repair/Reset option in Windows Settings, but Windows reported that the application could not be repaired/restored.

I subsequently uninstalled WinSCP completely and tried to perform a clean installation.

However, the clean installation from the Microsoft Store also fails with the same error 0x80073CF6.

The complete sequence was:

WinSCP repeatedly failed to update through Microsoft Store with error 0x80073CF6.
I restarted Windows.
The update was eventually installed.
After the update, WinSCP stopped launching.
The Repair/Reset option reported that the application could not be repaired/restored.
I uninstalled WinSCP.
I tried to reinstall it from the Microsoft Store.
The installation failed again with the same 0x80073CF6 error.

At this point, I cannot install the Microsoft Store version of WinSCP at all.

It seems there may be an issue with the deployment or installation of the MSIX/AppX package distributed through the Microsoft Store.

Could you please let me know if this is a known issue with the Microsoft Store package, or if there is a recommended way to diagnose what is causing the 0x80073CF6 error?

I can provide Windows version/build information, logs, screenshots, or any other information that may help investigate the issue.

Thank you!
