Furthermore, even if a "portable" version appears to function, it is typically unstable. The software's original code is not designed to run from a temporary directory or a USB drive. This can lead to frequent crashes, data corruption, and an inability to save or load projects properly. It is also important to note that GaussView 5 has specific system requirements, typically requiring Windows XP/Vista/7/8/8.1/10 (32-bit), about 300MB of free disk space, and 1GB of RAM.
