VirtualAcorn Updates

Read these instructions BEFORE trying to install any of these updates.

These updates allow older copies of VirtualRPC to be updated to include features/bug fixes that are already part of products we currently ship. In order to work out which updates (if any) need to be installed please read the following steps:

  • Firstly find your VirtualAcorn CD. There is a serial number printed on the CD, you need this number. The number you need is not on the RISC OS licence sticker.

  • Read down the list of updates below and find the first update with a CD serial number higher than the number printed on your CD. For example if your CD serial number is 11593 the first update with a higher number is 11678 - HostFS Jan 2009.

  • If you don't find an update with a CD serial number higher than the number printed on your CD then you do not need any of these updates. Do not read any further.

  • Having found the first update with a CD serial number higher than the number printed on your CD download it and then install it.

  • Continue installing each of the following updates down the list in sequence. You must not skip one. You must install them in the sequence shown. If you do not follow the instructions then the VirtualRPC might not function correctly and it won't be possible to install any future updates.

All of these updates are in Windows format and need to be installed from Windows. To install an update first quit VRPC, then download the update using Windows. Next find the update on your harddisc (using Windows). Then open the update (it will be in a .zip file) then finally double click on the update and follow the instructions on screen.

HostFS Upgrade

This update resolves a fault with a small batch of VirtualRPC-SE CDs (numbers 12019-VRP to 12028-VRPC inclusive) which have a faulty version of HostFS included.

This update is supplied as a Windows .zip file with replacement components and instructions.
