I have a company configured laptop that includes Adobe Reader XI but I need to convert PDF's to PPT etc. That is why I pay personally for pack. I dont want to pay again for this.
PDF Pack is a subscription so you do not need to pay again. You can use this service from Reader DC/11 in any desktop or in a browser.
