Purchase CDendro7.4+CooRecorder7.4 from SWREG.org

You always get the download information directly by email!

Ordering option: There is an Extended Download Service offered by SWREG. With this service, SWREG retains a copy of your download, for a period of a year, should you need it again in the event of loss, a computer crash, virus, etc. This service is already included on the order form. If you do not want it, you should remove/uncheck it from the form!

Paying by Visa (or equivalent) to SWREG is the fastest way to get the programs!
Paying by Visa is also the best way to avoid difficulties with e.g. wire transfers where ordering information sometimes is not properly included. In such cases SWREG may run into problems of connecting your transfered money with your order - which sometimes implies a delivery delay!

If you want to contact SWREG.org directly, go to the order form and scroll down to the rightmost bottom corner. There you will find a link to contact information.

Please notice the .org in the internet address of SWREG.org, as there is another company operating with a .com address!

TRIAL versions of CDendro and CooRecorder

Both programs are available as 30 days TRIAL versions. Though these are not fully functional as CooRecorderTRIAL can only save coordinates for at most 60 ring coordinates and CDendro can only show 120 year long diagrams. Points placed with the tool for automatic detection of ringborders in CooRecorder cannot be saved. Moreover, CDendroTRIAL cannot save collections of samples in decadal/Tucson format. Each program does not cost more than a book... - so why not buy the complete package at once.
