A: DigiPro and DMM were written in Microsoft VB6. Microsoft discontinued support for VB6 development tools some time ago, making bug fixes and further development nearly impossible. In addition, Microsoft warned that Windows 7 would not support for the VB6 runtime. In fact, there is some minimal VB6 runtime support in Win7, but it is certain that DigiPro and DMM will stop running in some future update of Windows.
For that reason, we developed DigiPro2 to replace both DMM and DigiPro. Development took over a year, but it is written in C# and is guaranteed to run on future updates of Windows. We encourage everyone to migrate to DigiPro2 sooner rather than later.
You can download a trial version of DigiPro2. It runs in advanced mode for 45 days, then it reverts to a basic version that you can continue to use.
