If you see an error stating that MFC100.DLL or MSVCR100.dll is missing when trying to run RollMaster Start, this means your Windows machine is missing a required Microsoft Visual C++ Redistributable Package.
To fix this:
Download and install the Microsoft Visual C++ 2010 Redistributable Package for Windows.
Use the 32‑bit version even if your computer is 64‑bit, as RollMaster Start requires the 32‑bit libraries.
After installation, restart your computer and try launching RollMaster Start again.
You can download the package directly from Microsoft here:
