Legacy Genealogy Software for Windows has stopped working

Update critical system drivers, in particular the video driver. The NVIDIA driver has been a problem with many users. If you have an NVIDIA driver:
1) Right click on the Legacy icon.
2) Select "Run with Graphics Processor"
3) Select "Integrated Graphics" as opposed to "High Performance NVIDIA Processor"
