If you are still using a legacy version of Pirouette, on July 1st the price to upgrade to the current version of Pirouette, version 4.5, will no longer be available. The cost will be the full retail price of Pirouette v4.5. Older versions (e.g., Pirouette 4.0) were designed and implemented for older Windows environments and have become less compatible with current Windows operating systems. If you are still using an older system that has not been upgraded to Windows 10, products like Pirouette 4.0 may still work. However, we are no longer fixing bugs or implementing enhancements. If you have an older version, we recommend you take advantage of the current upgrade rate before it goes to full price.
