Description cybermonktitan 2025-06-10 20:27:30 UTC 
Description:
I downloaded the Windows (Aarch64) build of LO 25.2.4. The downloaded MSI file matches the SHA256 listed in the online info. When I doubleclick the MSI, Windows Installer pops up in its initializing stage ("Preparing to install..."), then gives a big warning: "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package."

The Windows (Aarch64) build for LO 24.8.7 does install correctly and I can start Writer without issues]

This is on a Microsoft Surface with a Snapdragon X Plus CPU, running Windows 11.

Additional testing showed that LO 25.2.3 was not affected (I successfully upgraded), but the current alpha (25.8.0.0alpha1 dated 2025-05-19T17:15:30Z) also fails with the same error.

Steps to Reproduce:
1. Download installer for 25.2.4 on a Windows 11 Arm64 machine
2. Start the installer

Actual Results:
Installer can't be started (beyond standard Windows Installer initialization).

Expected Results:
Installation proceeds as normal.


Reproducible: Always
