How to install composer on denwer?

Question

Composer

Such a question, please tell me how to install composer on denwer?
I need to fix a project that I downloaded from git as a zip file and unpacked it into a folder on denver.
The project asks composer.
I went the easy way (or not?) - I use ComposerSetUp.exe for windows.
When launched, it asks you to select a directory that contains the php.exe file.
When I give him the Php5 directory in Apache, he says that he does not see the extensions, although they are also located in the ext folder.
Tell me, please, what's wrong?

Answer 1

you need to install the php5 and git extension package for denwer here
is the PS instruction go to OpenServer

Answer 2

Removed from curl -s silent mode, it became clear what the problems were)) - said that there was no openssl library, uncommented. Everything downloaded.
Thanks again.
