File access problems can cause a simulation to stop with an error. In particular
RunDynam simulations may stop with an error. When run again the simulation may stop with
an error but during a different year (or period) of the simulation. Generally, the year
in which the error occurs is unpredictable. Some causes of these problems are:
Anti-virus software interfering with file access. Some examples of how to exclude
simulation folders and temporary folder from on-access anti-virus scanning are here.
Windows 7 file indexing interferes with file access. Learn how to exclude simulation
folders and temp folders from Windows 7 file indexing here.
