corel draw 12 roll back

[jasonwillems]

I downloaded a trial of corel draw X3, but didn't think it was worth the money to upgrade. When that trail expired I uninstalled it and attempted to reinstall my previous Corel Draw 12. It starts installing, but after about a minute, the progress movies backword and it says 'rollback action'. Then it tells me it was interupted before it could finish installation.

I've looked for a way around this, and all I can find is people asking the same question without answers. Can anybody help me?

Thanks,
Jason
