When you perform a full clean install of iClone5 from version 5.1 onwards you will have both 32bit and 64bit versions installed. You should also have two icons on your Desktop identifying each version.
However if you have only patched your version of iClone from version 5.0 onwards, then you will not have a 64bit version. In this case you will need to uninstall iClone5 and then download and install the latest full version of iClone 5.5 from your Member Account. This will then give you both 32bit and 64bit versions (64bit operating system required).
Please Note: All your installed content packs and custom content will not be removed when you uninstall. We do advise always keeping a backup of your custom content in case of hardware issues.
