Apache not finding PHP Module

Hello! I've been working with HTML and PHP for a few weeks now.  For  
the times leading up to now, I've been working at home on my Windows 7  
computer and IIS. I had PHP up and running on my laptop perfectly  
fine, but I wanted to work with PHP at school, too.  I decided the  
best way to do that is have the server on my flashdrive, and that  
Apache was the best choice. I got it working and portable (amazingly),  
but when I attempted to add a PHP handler, it wouldn't run. This is  
the error message I get:

httpd.exe: Syntax error on line 500 of F:/Apache/conf/httpd.conf:  
Cannot load F:/Apache/PHP/php5apache2_2.dll into server: The specified  
module could not be found.

This is exactly what I added to httpd.conf:
# PHP 5
Loadfile "PHP/php5.dll"

# Load the module
LoadModule php5_module "PHP/php5apache2_2.dll"

# configure the path to php.ini
PHPIniDir "PHP/"

AddHandler application/x-httpd-php .php
AddHandler application/x-httpd-php-source .phps
<FilesMatch \.php$>
      SetHandler application/x-httpd-php
</FilesMatch>

What I've done so far:
1) I made sure that php5apache2_2.dll is in the place I said it was. I  
don't know if this makes a difference, but I downloaded the V6 Non- 
Thread Safe version of PHP which didn't have that file, so I copied it  
from the Thread Safe version (along with some other similar files).
2) I looked at the user feedback and tried some of that stuff out, but  
Id like to keep PHP as a handler (I know it's possible).
3) I made sure that the line the error was referring to was in fact  
this line:
LoadModule php5_module "PHP/php5apache2_2.dll"
4) I took note of the fact that application/x-httpd-php .php and  
application/x-httpd-php-source .phps were missing from mime.types, but  
my mentor (who was helping me at the time) told me that was irrelevant  
at the moment, so I didn't bother with it yet.

Is there anything I'm missing? It seems I do that sometimes, then  
can't for the life of me figure out what's wrong.
