Microfin Technical Support Website



PLEASE READ THIS!!!!!! After 17 years of maintaining the Microfin website and providing free technical assistance on this free software to thousands of people around the world, as of January 2014 I have to announce that I will no longer do either.

The wesite will remain online for some time, unmodified. The software and training materials are here for you to download. I will not be doing updates to the wesite or the software, and I won't be responding to technical support emails. There is the Microfin Listserve available for you to post questions, but you will also find 90% of the answers to your questions written right inside the software itself or in the detailed user's manual.

Thanks to all of you for you support and appreciation though these many years.

Chuck Waterfield
