How to upgrade

To qualify for the special upgrade price you will need to return your original VirtualRPC-AdjustSA CD. The DVD case, colour cover, installation guide and RISC OS 4 licence sticker do not need to be returned.

The upgrade process works like this:

  • You complete the purchase and pay for the upgrade on-line with a debit/credit card.
    You can pay with a cheque from a UK bank (payable in Sterling) made out to 3QD Developments Ltd. Include the cheque when you return your old product.
  • You return your old VirtualRPC-AdjustSA CD, include your name, address, phone number & the upgrade you would like.
  • We then send you out the 'new' VirtualRPC-AdjustSA CD (and any other components that are required).
  • You install the new VirtualRPC-AdjustSA and then contact us for an unlock code.
  • You can keep using the Windows version for 30 days while you tranfer your files and settings.

Once your old CD arrives at our offices we will process the order. We strongly recommend that you use a tracked/insured service to return your CD. If it doesn't arrive at our offices we won't be able to process the upgrade and you may end up having to purchase a new copy of VirtualRPC.
