composer windows Install composer

[Gragia79]

Goodmorning everyone,
I have the version uniserver zero XIV and unicontroller XIV
I would like to install composer.
With the composer windows installation I selected C: \\ UniServerZ \\ core \\ php74 \\ php.exe for php.
gives me the following errors:
Program Output:

 in Unknown on line 0

I have enabled all the listed dlls in the php.ini file, but it keeps giving me error.
What can I do?
