Windows 7: HIQ Recorder on Windows 7 not properly working

I recently installed Windows 7 on my computer, Dell Vostro 1400. Now the HIQ recorder (roemersoftware) and skype do not work properly.
The recorder records all sounds: from the mp3 file and from the microphone. When I mute the microphone the recorder software tells me i do not have a sound card.
Any clue how to get this fixed.
Skype: I can see the partner and the partner can hear me. But I cannot hear my partner. Skype or Windows problem?
Can someoen offer help?
Thanks,
Henry

Dell ONLY supports Vista 32 bit on this model, however in most cases the Vista drivers all work in Windows 7 (as long as you have Windows 7 32 bit).

On a new install the correct and required install sequence on a Dell is (1) Install OS (2) Install Dell Laptop Support Software (on applicable models) (3) Install motherboard chipset drivers (4) Install Device Drivers including sound, video, ethernet, etc.

The motherbord chipset drivers are key to a successful install and there are two chipset drivers listed on the Dell downloads - and Intel and a Ricoh. One of the main things the chipset drivers do is define (identify) all the devices on the motherboard. If you skipped the chipset drivers, install them and then the sound and anything else that is missing.
