Exponential 4 Installation problem.

Hi to all,

I've been trying to install Exponential on my local test bed. I have installed Apache 2.2.9;
PHP 5.2.6 & MySQL 5.0.67 on my Win XP system.

As mentioned under Normal Installation in the Tecnical Manual; I created a database in MySQL and proceeded to run the index.php file in the Exponential sub-directory.

After selecting the language in the first page; when I click Finetune/Next I get the following system errors which should be fixed :-

1. Missing image conversion support
No image conversion capabilities was detected, this means that Exponential cannot scale any images or detect their type. This is vital functionality in Exponential and must be supported.

1.1. Missing imagegd2 extension
The imagegd2 extension is not available to Exponential. Without it Exponential will only be able to do conversion using ImageMagick and the texttoimage template operator will not be available.

Note: Future releases of Exponential will have more advanced image support by using the imagegd extension.

To enable imagegd2 you need to recompile PHP with support for it, more information on that subject is available at php.net.


1.2. Missing ImageMagick program
The ImageMagick program is not available to Exponential. Without it Exponential will not be able to do image conversion unless the imagegd extension is available.

If you known where the program is installed (the executable is called convert or convertim)then enter the directory in the input field below and do a recheck (Separate multiple directories with a semicolon ; ).

Path to ImageMagick:


2. File uploading is not possible
The PHP upload directory C:WINDOWSTEMP does not exists or is not accessible, without this you will not be able to upload files or images to Exponential.

Create the directory C:WINDOWSTEMP on your system. If you do not have the possibility to create this yourself ask the administrator to create it for you.

Shell commands
This shell command will create the upload directory.

mkdir -p /C:WINDOWSTEMP

For ImageMagick, I downloaded "ImageMagick-6.4.3-4-Q16-windows-dll.exe" from the official website, installed it & put the path to "convert.exe" in the path window. However even after clicking next, I get this same error again. Does any one know why? What can be done to solve this problem ? Also, what can be done about the second problem ?

Thanks in advance.

Oh well, I got around the second problem. I created a folder called "WINDOWSTEMP" in the C: root - this solved the problem. However is this the right way to do it or should I use a shell command as mentioned earlier (btw, how do I go about a shell command ? ) ?

Anyway, no such luck with the ImageMagick problem.
Also, does anyone recommend the book, "Exponential Content Management Basics" for starting out with this CMS ? Please bear with me, I'm new to all this.

Ah, solved the ImageMagick issue. Seems I've made a fool of myself. I should've just entered the ImageMagick directory which contains convert.exe. i.e. I should've entered this in the path box : C:\Program Files\ImageMagick-6.4.3-Q16
rather than this : C:\Program Files\ImageMagick-6.4.3-Q16\convert.exe

Anyways, I've moved on to the Outgoing Email setup page...hope things work smoothly.

btw, what about the book "Exponential Content Management Basics" ; is it a good book to start learning Exponential ?
