This software did not work on my Vista Home PC. Gives the following error.
'Component 'THREED32.OCX' or one of its dependencies not correctly registered "
a file is missing or invalid.'
But I appreciate any tool available online. If these can be made available
online - so one do not have to download and install that will be better.
