So, when you go to use the product, you are directed to an "update" which is an add for a product.
When you finally get to the right page, download the product and install, the installer:
a. launches the default browser
b. loads an inane page "thank you for installing..." and more adverts.
Is this intended to create a positive affect toward the company? Isn't this a "hard sell"? It makes me sad to see a company with a good product who makes a freeware/no cost version available establish such a negative appearance.
Making use of your product a painful experience is no way to encourage users to invest in an enhanced version. It demeans the product, and makes the company appear duplicitous. Why be so self-defeating?
