This page is about the digital id software Bankid or BankID. The underlaying application of Bankid is Nexus Personal (http://www.nexusgroup.com), so the tips here is probably helpful for anyone trying to run other versions of Nexus Personal as well.

Running Bankid in a virtual machine running Windows
If no other solution works, you can always install for example VirtualBox and run Bankid on a Windows virtual machine. It should work fairly out of the box with Windows XP on the guest. If you want to use a card-reader you have to add the user that runs Virtualbox (usually you) to the group
vboxusers to be able to access the usb-connected card-reader. You can then add a usb-filter in the Virtualbox settings for the machine, so that the machine captures the card-reader automatically.
