libCompiler not populating .css & .js files

I have just downloaded DHTMLX Suit 3.0 and decided it was time to get libCompiler working. I am a .NET developer and have never worked with PHP before. My devlopment machine is running Win 7 Pro x64. I set up PHP on IIS and created a simple test page and it works.

I then created a new directory “dhtmlx3” in Inetpub/wwwroot and copied the full contents of v3 Pro Suite into it. I browse to localhost/dhtmlx3/libcompiler/index.html, select the components I want (Grid, Windows, Combo and Tabbar together with the dependencies it includes) and click “Generate”. Things happen and after a couple of seconds I the message “Ready code stored at ./export/1310394211”. I then browse to the newly created directory, but the generated dhtmlx.css (0kB) is empty and dhtmlx.js (1kB) only contains a copyright message - no code.

Here is the contents of the manifest.txt:

Please help with why all appears well, but the .css & .js files are not being populated.

New version of libCompiler requires java for code compression.
You can update images.php in the libCompiler with the attached one. After that if java is not available it will fall back to more simple compressing logic.
images.php.zip (2.82 KB)

Thanks, that has generated the files.
