Thanks Grace for raising this question as many others will have the same question. Our current version doesn't work on Vista. However, we are about to launch a new version whch will be Vista compliant. We are currently testing the new version and it should be launched in 1-2 weeks.
Those who are currently buying our present version will be able to freely upgrade to the new version.
I hope this answers your question. Please write to us at email@example.com
for any more questions you may have about our products.
