Running the following test using .NET

public async Task Test1()
{
    using var playwright = await Playwright.CreateAsync();
    await using var browser = await playwright.Chromium.LaunchAsync(new() { Headless = false });
    var page = await browser.NewPageAsync();
    await page.GotoAsync("https://playwright.dev/dotnet");
    await page.ScreenshotAsync(new PageScreenshotOptions { Path = "screenshot.png" });
}

Results in following error

Running PrintDeps.exe results in the following:

PS C:\PlaywrightDemo\node_modules\playwright\bin> .\PrintDeps.exe C:\Users\UserName\AppData\Local\ms-playwright\chromium-888113\chrome-win\chrome.exe C:\Users\UserName\AppData\Local\ms-playwright\chromium-888113\chrome-win\chrome.exe
    KERNEL32.dll => C:\windows\System32\KERNEL32.DLL
    VERSION.dll => C:\windows\SYSTEM32\VERSION.dll
    chrome_elf.dll => not found

And again checked chrome_elf.dll is still available

First of all thank you for your quick response.

I completely removed the ms-playwright folder and reinstalled. Because I am behind a corporate proxy the playwright install command fails.

Failed to install browsers
Error: Failed to download chromium, caused by
Error: connect ETIMEDOUT 13.107.246.67:443
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1144:16)

I have installed the Browsers using the command: npm i -D playwright

This again downloads chromium, ffmpeg, firefox and webkit. I can start chrome.exe from the chromium-888113/chrome-win folder.

chrome_elf.dll is present

Test still fail with same error: Host system is missing dependencies! (chrome_elf.dll)
