Chess Game Analyzer Creatica

Haven't heard of him. As I said on my web site, I was inspired by chess.com analysis but it is equally possible that chess.com got influenced by Ferdinand Mosca )

Wow! Very nice job!

I'm having a lot of trouble trying to figure out how to install and use it. I've got the fact that I need to run the application as administrator, but after that I just get confused and don't understand what the instructions mean.

Sorry for your trouble, Dazzles. I'll try to make the instructions clearer. But basically, all you need to do is to:
1. Download the chessgame-analyzer-2.4.0.0.zip file
2. Unzip it into chessgame-analyzer-2.4.0.0. folder
3. Download coreinfo.exe from sysinternals and save it in chessgame-analyzer-2.4.0.0 folder
4. Go to that folder
5. Right click on the chessgame-analyzer.exe file and select "Run As Administrator"
6. Assuming you download your pgn games to Download folder, go to Downloads.
7. Right click on your lichess.pgn file and select "Analyze with Stockfish"
8. Wait until the analysis is complete
9. The resulted lichess-analyzed-by-stockfish.pgn file will be opened in your default chess GUI, assuming your have one installed. Otherwise, you will be prompted to select an application.

Many steps and words but in reality, it is just couple of mouse clicks.

Ah, thank you! I got it to work. Unfortunately, when I went to analyze a game, first stockfish crashed and then the app crashed.

I updated the web site with better installation, configuration and usage instructions.
Dazzles, you may want to run the chessgame-analyzer.exe from the command prompt to see why it crashed. The command line syntax is the following:
chessgame-analyzer.exe stockfish <lichess.pgn>
