[Bug]: Portable Version installs when newer version available (Update functionality)

[EpicGazel]

Preflight checklist

• I have searched the issue tracker for a bug report that matches the one I want to file, without success.
• I have searched the frequently asked questions for a solution that fixes this problem, without success.
• I have checked that I'm using the latest stable version of the app.

What app version are you using?

v5.0.12

What operating system version are you using?

Windows

Expected Behavior

The portable version should not attempt to and successfully install an updated version upon closing.

Actual Behavior

While running the portable version, an update will be found, downloaded, and installed upon closing. This adds files and a desktop icon, all of which are unprompted.

Screenshots

No response

might not be directly related but the winget repo uses the portable instead of the installer , I can update that if you want

Review if you want it: microsoft/winget-pkgs#152606

this should be fixed in 5.1.2, but since it's fixed in that version, we'll need to wait for 5.1.3 to verify if it was actually fixed

[EpicGazel]

Still not fixed going from 5.1.3 -> 5.1.4

[EpicGazel]

Still not fixed going from 5.1.4 -> 5.1.6

this is unlikely to be fixed, since it's an issue with electron build dependencies, not miru itself

[EpicGazel]

Band-aid solution for others: delete or rename %localappdata%/miru-updater
Remove user permissions from %localappdata%/miru-updater, then miru won't be able to download or access the installer.
No installer.exe means no install.
