As of November 15, 2014, Hamar Laser will release a final build of our Couple6 software for our customers who still use Windows XP. Due to support issues with foreign language versions of Win XP, we need to switch to .Net 4.5 Framework, which is not supported in Win XP. All future updates to Couple6 will only support Win 7/8 operating systems. To continue to receive future Couple6 updates, upgrading to Windows 7 will be required. Of course, this will not affect users who currently run Couple6 on a Windows 7/8 machine.
