You really do seem to be in serious denial about your own incompetence, so I’ll just lead you to it by hand. On September 3rd at 2:17 P.M. @Gary posted the following:
on 2020-09-02, I was able to download (key is displayed on download page, plus it arrives in an e-mail) the file, which is a ZIP file. Make sure you extract all of the contents of that ZIP file, and place them in a regular folder. A simple way to do this is to open the ZIP file (double-click), select all (Ctrl+A), then copy to the clipboard (Ctrl+C), then use the Backspace key to step up (out of the Zip file), then you can paste what you can have copied to the clipboard into the folder you are now in (Ctrl+V), or move to any other folder and do the paste (Ctrl+V). Just make sure you have all of the files from the ZIP file together (or it will not work).
When you have all files accessible, double-click the setup file. Right after agreeing to the license, you will get a prompt to install the C++ Redistributables (based on its determination that you do not have them). Let the setup install them or it will not work. A lot of people think they already have them but the setup does the check the correct way Microsoft dictates. It does not matter if you think you already have them or not, let the setup install them (even if you did already have them, it will not hurt to install them a second time). If the setup program determines that you already have them installed, you shouldn’t get prompted at all. Regardless, it takes only a few seconds to get past that part.
Proceed through the remaining steps until you get to the activation page asking if you want to activate via the Internet or by e-mail. Either way, Soft Xpansion needs to know what the hardware key is for your computer. They will send the 16-digit key to their servers to activate the program. You will need to enter the 8-digit license key that was displayed to you on the download page and also sent to you in an e-mail. When the program has been activated, you will be told.
Next, Soft Xpansion wants you to reboot your computer. This is to ensure the Microsoft components are all connected and working. In most cases, the program will work whether you reboot or not. If anything does not work, then do a reboot and try again.
Your own drivel which I quoted was posted nearly 5 hours later.
Several of the other posts made it clear that the posters had not followed the directions above and instead of trying to figure out why they had not succeeded ran off into the weeds (as you did) trying to mix the free offer here with the trial Perfect PDF offer on its Web site (hardly a recipe for success given that they were totally different). All of that babble was, of course, completely extraneous to the issue of whether the offer here worked.
As I suspect there’s something general to be learned from these interchanges I’ve been continuing the discussion here, but if you’d prefer to move it over to the Perfect PDF discussion I’m fine with that and will copy this there for a start.
