Answer 1

You are looking for the file in the current working directory, you can use the getcwd command to see what your working directory is.
1)
echo getcwd() . "\n";
http://www.php.net/manual/de/function.getcwd.php
Furthermore check if you have permission on that file.
2)
is_readable($filename)

Answer to your updated question (in future, please close answered questions and ask a new question)
You're using the Excel5 Writer
$objWriter = PHPExcel_IOFactory::createWriter($objTpl, 'Excel5');
Which is used for writing BIFF format files, which should have the extension .xls
But you're saving the file with a .xlsx extension
$objWriter->save('template1.xlsx');
which is for OfficeOpenXML format files
BIFF files are created using the Excel5 Writer, and have an extension of .xls
OfficeOpenXML files are created using the Excel2007 Writer, and have an extension of .xlsx
Don't mix and match, writers and extensions aren't interchangeable
