我想在我的模板中包含一个pdf to excel转换器？

I already have a pdf-to-excel converter in my program files. I want to get it from url. I tried the following:

<a href="<?php echo base_url();?>assets\pdftoexcel\PPTECMD.exe">click here to convert</a>

but the software is downloaded. I want to open the converter window by clicking the link. How can I do it? This is the list of pages in my program file (pdf-to-excel):

Boxofttoolbox.exe
MMPDF.exe.
jbig2dec.exe. etc..
