How can you make money with your program?

Question

C++ / C#

1) Make it paid, but people in the CIS are not yet ready to pay for software in bulk, so it's not an option
2) Embed advertising in it? But with the help of what service and how much is it cost-effective?
3) Donations, but will they be at all?

Answer 1

4) Sell support and "individual" completions of your software for the buyer.
More can be said if you tell us what your software does.

Answer 2

1. If your program solves any user problem well and at the same time its price is not in the clouds, then people will buy it.
And what limits you to sell it outside the CIS?
2. In order for advertising to bring you at least something, you need mass character.
3. It seems to me that donations should not be counted on.
