如何找到 tesseract.exe 的路径？

我试过这个，但没有找到，我之前成功地将它用于 python.exe：

var path = Environment.GetEnvironmentVariable("PATH");
            string myPath = null;
            foreach (var p in path.Split(new char[] { ';' }))
            {
                var fullPath = Path.Combine(p, "tesseract.exe");
                if (File.Exists(fullPath))
                {
                    myPath = fullPath;
                    break;
                }
            }

            if (myPath != null)
            {
                Console.WriteLine(myPath);
            }
            else
            {
                throw new Exception("Couldn't find myPath on %PATH%");
            }

所以我尝试了：

var allExePaths =
                from drive in Environment.GetLogicalDrives()
                from exePath in Directory.GetFiles(drive, "*.exe", SearchOption.AllDirectories)
                select exePath;

但它会引发错误：拒绝访问路径“C:\Documents and Settings”

public static string GetFullPath(string fileName)
{
    if (File.Exists(fileName))
        return Path.GetFullPath(fileName);

    var values = Environment.GetEnvironmentVariable("PATH");
    foreach (var path in values.Split(Path.PathSeparator))
    {
        var fullPath = Path.Combine(path, fileName);
        if (File.Exists(fullPath))
            return fullPath;
    }
    return null;
}
