The message already says all: The value may not be greater than the max-value.
Just add a condition before you increment the value:
if (trackBar1.Value < trackBar1.Maximum)
trackBar1.Value++;
Or here your complete event handler:
private void button41_Click(object sender, EventArgs e)
{
if (trackBar1.Value < trackBar1.Maximum)
{
trackBar1.Value++;
label27.Text = trackBar1.Value;
}
else
{
MessageBox.Show("Max value = " + trackBar1.Maximum);
}
}

solved Maximum value in the track bar
