LABPS3005DN problem with driver

I have tried to install PC-software for LABPS3005DN on a Compaq running on Win-XP.
When installing driver pack for (X86) it resulted in a message that the “Installation failed” mentioning the name of the driver as “Silicon Laboratories Inc”
I tried the installation on two different laptops both running XP.
Have others had the same problem?
Are there any driver pack for Win-XP.

What can I do?
