I have an Acer L5100 micro PC which has a laptop style PCI-E slot on the system board. I have successfully installed a wireless network card before so I know the slot functions.
I purchased the LR534 to use in this system but when installed it does not even auto detect. The suppler has sent me a replacement in case the original was defective but to no avail, still not being detected.
I have tried with the RC of windows 7, vista home premium and XP-PRO MCE all of which fail to detect any tuner card nor does the card show up in device manager.
The lifeview site shows no support for  this card and the Packard Bell site only gives a driver for XP (which has been installed and re-installed with no joy)
I will be testing the card in the PCI-E slot of a desktop later to see if it is detected in there.
Anybody with any experience of similar problems or of this card in paticular out there?
