install4j MSI安装器UAC提示显示随机文件名，如何配置为应用名称？

Absolutely! You can configure the display name shown in the UAC prompt when using install4j to create MSI installers—no more random strings like 2e5658ae.msi popping up. Here's exactly how to fix it:

• First, open your install4j project and navigate to the Media tab. Select the MSI media configuration you want to adjust.
• Switch to the MSI Identity sub-tab in the right-hand panel. This is where you define core metadata for your MSI. Fill in the Product name field with your actual application name (e.g., "My Awesome App v2.0")—this is what will show up in the UAC prompt. Don’t forget to double-check the Manufacturer and Product version fields too, as these help with proper system registration.
• Next, go to the MSI Options sub-tab. Look for the UAC section, and set the Request execution level to Require administrator (if your installer needs elevated permissions, which it likely does to trigger UAC). This ensures the UAC prompt correctly ties back to your application’s metadata instead of the temporary MSI file.
• Finally, rebuild your MSI installer. When you run it, the UAC prompt should now display your configured application name instead of the random temporary filename.

Why this happens #

By default, install4j embeds the MSI package inside a bootstrap executable. When launched, it extracts the MSI to a temporary directory with a random filename to execute it. If you don’t explicitly set the product identity metadata, Windows can’t associate the temporary file with your app, so it shows the random filename instead.
