If a previous un-installation did not finalize correctly, you may find yourself in a state where a newer version of TransMagic is asking you to un-install an older version, but the older version can not be un-installed.
WARNING do not continue without reading this! Modifying the registry can result in corrupted data, or even destroy your installation of Windows. If you are un-experienced with modifying the registry it is highly recommended that you defer this task to someone who is.
In this state you will need to preform a manual un-installation by deleting a registry key. Below is the complete list of all un-install keys that TransMagic is looking for. The most recent keys are listed first. The un-install keys that TransMagic R8 is looking for are under:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Then if any of these sub-keys exist, then delete them then reboot:
