I'm running under Windows Server 2008 and IIS.
I've installed Tiki OK, but found Composer hadn't installed.
So I found this page https://dev.tiki.org/Composer and the Note for Windows Users at the bottom of section 1.3.2 and went for option 2, the global install.
I downloaded composer, it starts up OK from the command prompt in the Tiki folder, and is in the path.
I then went to the Tiki folder and ran composer install
This gave the following screen messages:
''Loading composer repositories with package information
Updating dependencies (including require-dev)
Nothing to install or update
Generating autoload files
No obvious error messages, so I assume all is OK.
But then I run tiki-check.php and under Tiki Packages it says Composer not found
Also, under the Admin menu I go to the Packages page. Again it says Composer not found.
If I click on Diagnose Composer it just comes back with Composer not found.
If I click on Install Composer it says Error - There was a problem installing composer
Many thanks for any suggestions,
