Then I clicked the msi installation file of php again and installed it as a module. now I clicked all the extension options that were not selected last time and installed all the modules. haha, I installed them all. Or the last configuration file. Test: apache is normal, html is accessible, php fails, and access to php becomes a file download prompt.

I also crashed, whining, and asking for a big fairy solution.
