# The secret thing about PVS\-Studio

There exists the PVS\-Studio code analyzer\. It integrates into the Visual Studio 2005/2008/2010 environment and allows you to detect errors in C/C\+\+/C\+\+11 programs \(see samples of errors it can detect\)\. Regarding its advantages, we can note usability, detailed documentation, on\-the\-fly analysis and the best diagnostics of 64\-bit errors\.

## The reason for the secret

Unfortunately, being one of the PVS\-Studio's creators, I'm sad about the number of the distribution package's downloads from the site\. They are very few\. I see the reason: people are accustomed to thinking that it's not so easy for a programmer to try a commercial analyzer\. You have to deal with the commercial manager at first and only then you might be allowed to get the demo version\. I think many people even don't try to visit the Download page waiting to see a huge fill\-in form or a message kind of "if you want to try, write to us"\.

We don't approve this method\. We believe that a person should be able to easily try and purchase a software product\. Our opinion completely coincides with the one of Alex Payne who has written the article "[How Not To Sell Software in 2012](https://www.al3x.net/blog/2012/02/29/how-not-to-sell-software-in-2012)"\.

## The secret

The secret thing about PVS\-Studio is that nobody knows that you can easily try and purchase it\. Moreover, PVS\-Studio can be used for free at first\. The version you download from the site is completely full\-function\!

The demo version's restrictions will only occur when you have fixed 100 errors in your program using our tool\. If your project is small or contains just a few errors, you will be able to use PVS\-Studio without purchasing a license\. But if you have fixed 100 errors in your program with PVS\-Studio, it's fair that you buy a license to go on eliminating both old and fresh errors\.
