[bug] Tauri 2.0 cannot run on Windows 7 SP1(x86 or x64)

[kingyang]

Describe the bug

The compiled result of Tauri 2.0 does not run on Windows 7 SP1.

Reproduction

Run pnpm create tauri-app

Expected behavior

It is expected to run normally. I also want to know if Tauri 2.0 supports Windows 7. Globally, Windows 7 still has a 3% market share, and in some regions like China, the share is as high as 20%. This is a significant proportion.

Additional context

I compiled on both Windows 8 x86 and x64 environments, and tested on Windows 7, but it still could not run.

The apps have been installed in Win7:

Can you translate what the dialog says? Or at least copy paste the text so we can translate it ourselves?

Thanks!

@FabianLars
I made some new attempts.

Build environment:
Windows 7 SP1 x64
(pnpm tauri build run error, the possible issue is with cli.win32-x64-msvc.node in @tauri-apps/cli)

Test 1:
cargo build --release (x86_64-pc-windows-msvc)

Runtime environment:
Windows 7 SP1 x64: Runs normally
Windows 8 SP1 x64: Runs normally

Test 2:
cargo build --release --target i686-pc-windows-msvc

Runtime environment:
Windows 7 SP1 x64: Abnormal
Windows 7 SP1 x86: Abnormal
Windows 8 SP1 x64: Runs normally
Windows 8 SP1 x86: Runs normally

Build environment:
Windows 11 x64

Test 3:
pnpm build (1.77.2 x86_64-pc-windows-msvc)

Runtime environment:
Windows 7 SP1 x64: Runs normally
Windows 8 SP1 x64: Runs normally

Test 4:
pnpm build -t i686-pc-windows-msvc (1.77.2)
Runtime environment:
Windows 7 SP1 x64: Abnormal
Windows 7 SP1 x86: Abnormal
Windows 8 SP1 x64: Runs normally
Windows 8 SP1 x86: Runs normally

[FabianLars]

That looks a bit like an issue with the rust compiler or something 🤔

Thanks for the extensive testing! I'm still out sick for a while so I can't look into it right now :/

@FabianLars
Wishing you a speedy recovery. I feel the possible issue lies with wry or tauri-runtime-wry, specifically regarding compatibility with Windows 7, because I have tested some programs under Tauri 1.7 that run normally on Windows 7.

[kingyang]

Project wry:
cargo build --release --example simple
Runtime environment: Windows 7 x64
simple-1.77.2-x86_64-pc-windows-msvc-by-win11-x64.exe runs well.
simple-1.77.2-i686-pc-windows-msvc-by-win11-x64.exe throws an exception(the same error occurs on Windows 7 x86 ):
RUST_BACKTRACE=full ./simple-1.77.2-i686-pc-windows-msvc-by-win11-x64-raw.exe thread 'main' panicked at .....\tao-0.29.1\src\platform_impl\windows\event_loop.rs:708:5:
assertion failed: subclass_result.as_bool() stack backtrace: 0: 0x109bc3b -

[kingyang]

Now the issue points to tao-0.29.1\src\platform_impl\windows\event_loop.rs:708:5

@amrbashir @FabianLars
Could you please reopen the current issue as 'Open'? Thank you.
