The only logical explanation for this error is that the operating system your new PC uses, is not compatible with the available drivers for the webcam. As I can see on Google, there is no compatibility for Windows versions beyond XP. However, try installing it using the manual way. Start Device manager (Start > Run > devmgmt.msc) and locate the webcam. Right click it and select Update driver. Point it to where the INF files(driver) are and proceed with the installation. Windows will give you a warning, but simply ignore it.
