Used PD3 (everything was OK) and ugraded it upto PD4. My VM from PD3 has been backuped and transfered but now, when I start windows there is a message - " cannot find dirver for ethernet controller". I have tried all the combinations - shared with defaul adapter, bridged with all types of adapters - the resul is the same - no adapter is connected.... Also I have tried to install the driver from /../system32 and windows installation CD. The result is - no driver found. Please help, I'am really lazy to reinstall my VM totally and without guarantees that everything will be OK.
Please try to install Parallels Tools. They will install the network driver together with many other features. It can be done from the menu of Parallels Desktop
