Installation of Chronoforms in Joomla 1.5.11

[nicsi76]

I heard a lot of good things about Chronoforms but unfortunately I can't even manage to install the component to my Joomla Installation. I tried the automatic installation with the zip-file from my computer, tried it with the installation path with the zip file and also via the installation path with an unzipped folder. The automatic installation brings out a "Script Error"-page, while the other two options complain about a package directory they need for installation.
I had installed components before without any problem...
I also tried with both gzip-setting options...

Any help is highly appreciated since I'm already totally frustrated by trying to write a registration form on my own...

Here are my system's settings:

Hi nicsi76,

I'm guessing that the problem is that you are using PHP4. It's now so out of date that I think parts of ChronoForms may assume PHP5 is in use. Can't be certain as I haven't run PHP 4 for a long time.

Thanks for the hint.
I got an older installation file from my sister which works fine.
