[mpeter50]

Is there an existing issue for this?

• I have searched the existing issues

Platform

Windows

OS version

10

App version

v5.7.1

Current Behavior

When starting the desktop app either with the desktop icon, or with directly running simplex.exe in the instalaltion directory, I get an error message that says "Failed to launch JVM", and the desktop app does not start.

The desktop app does not produce log output, even when started from the terminal, and I don't know where it places them.
%APPDATA%\SimpleX\ does not contain log files.

Expected Behavior

The desktop app should start when it is started

Steps To Reproduce

1. Install said version with the MSI image: https://github.com/simplex-chat/simplex-chat/releases/latest/download/simplex-desktop-windows-x86_64.msi
2. Try starting the desktop app

Relevant log output

No response

It might be an important detail that I have installed the software to an other drive than C, but I have allowed the installer admin permissions.

I have did some testing, but wasn't able to start the desktop app.

I have uninstalled it using the uninstaller in the control panel's programs and files menu.
Then I have installed the same version with the same installer, but now with the default settings, so it was installed to drive C now.
Starting the app results in the same error message.

I also tried to start the app manually from the command line, with the JAVA_HOME environment variable set to a copy of the AdoptOpenJDK's JRE 16, but it results in the same.

Is there any parameter or an entry in a setting file I could use to make it emit some logs about the issue?

The earliest version I have found to have the desktop app for windows, 5.4.0, behaves the same way.
