RunDynam stops with the error "Unable to launch solution process".

File access problems can cause a simulation to stop with an error. If your RunDynam simulation stops with the error message "Unable to launch solution process" the problem may be caused by your anti-virus software. Try adding an exclusion to your anti-virus software settings. Some examples of how to exclude a simulation folder, the temp folder, and a specific program like RunDynam.exe from on-access anti-virus scanning are here.
