Any documents about how to make tauri 2.0 support Win 7?

[crackleeeessyp]

Are there any documents that showing how to make tauri 2.0 support windows7? I tried latest version, it shows error:

Any suggestions such as rust version, dependencies version, or configurations I needs to adjust to make it work?

rust version

For rust use 1.77.2 - it's the last one with full win 7 support. After that you'll have to use the special windows 7 rust target (<arch>-win7-windows-msvc) but it's not Tier 1 anymore.
Edit: This ^ should fix the error in your screenshot.

dependencies version

Tauri v1 and v2 and all the plugins should still support win 7 as they are, including "inner" dependencies.

or configurations

https://v2.tauri.app/distribute/windows-installer/#supporting-windows-7 - On top of that, don't use transparent windows. That's the only thing that comes to mind right now.

hi. I tried to compile tauri to win7。However, the following exception occurs。
error: package cargo-platform v0.1.9cannot be built because it requires rustc 1.78 or newer, while the currently active rustc version is 1.77.2

Use the cargo tree command

discover tauri-utils use cargo-platform v0.1.9

this my Cargo.toml

`
[dependencies]
tauri = { version = "2.1.1", features = [ "tray-icon", "image-png"] }
window-shadows = "0.2.2"
tokio = { version = "1.41.1", features = ["full"] }
tauri-plugin-os = "2"
tauri-plugin-notification = { version = "2.0.0", features = [ "windows7-compat" ] }

tauri-plugin-dialog = "2"
tauri-plugin-process = "2"
tauri-plugin-log = "2.0.0"
tauri-plugin-autostart = "2.0.1"
tauri-plugin-single-instance = "2.0.1"
tauri-plugin-updater = "2"
tauri-plugin-window-state = "2"
tauri-plugin-shell = "2"

`

What am I supposed to do now?

If that happens you'll have to use cargo update to downgrade these packages in your lockfile. For this package it's this for example

cargo update -p cargo-platform --precise 0.1.8

I assume there will be more, so to do the rest yourself, simply look up the versions here https://crates.io/crates/cargo-platform/versions (replacing cargo-platform with the crate you need). If the crate didn't specify rust-version you often can check out the changelog in their github repo. If that's also not helpful you'll have to do trial and error.

That's OK now. Thank you for your reply
