Select the latest stable version. (Note: Ensure you download the 64-bit version if your operating system supports it, as it allows the software to utilize more RAM and prevent out-of-memory crashes).
Stacking dozens of high-resolution image files requires significant RAM. If DSS crashes mid-stack, go to Stacking Parameters > Temporary Files and make sure the directory points to a hard drive with plenty of free storage space (preferably an SSD). Alternatively, reduce the number of images or use the Custom Rectangle tool to stack only a specific region of interest.
