My Desktop has MySql and Apache already installed and then I installed  
InstantRails on it without any trouble. Incase of my laptop I have both  
the softwares already installed and when I install InstantRails 1.7 and  
try to run it gives me all sorts of errors.

Unknown():null():unable to initialize module  
Module comiled with module API=20060613, debug=0, thread-safety=1  
PHP compiled with module API=20020423, debug=0, thread-safety=1  
These options need to match

Apache.exe -Unable to LocateDLL  
The dynamic link library php\_mbstring.dll could not be found in the  
specified path

unknown():Unable to load dynamic library ‘D:\PHP\ext\php\_exif.dll’ - The  
specified module could not be found

I get the same errors with InstantRails 1.6

I would really appreciate any pointers.

Thank you

Syed

I don’t know the answer to your problem, Syed, but both Apache and PHP  
aren’t really necessary for InstantRails. They run only to perform  
PHPMyAdmin.

Like you I already had PHP and Apache and MySQL installed separately on  
my system so I just used the Rails and Rails\_Apps directly from Instant  
Rails and didn’t bother with the Instant Rails EXE or anything itself.

Once you’ve unzipped it you’ve effectively installed everything (barring  
adjusting a few configuration files I think) so you can just go about  
coding.

I installed the Aptana RadRails thing to work with, also.
