Installation files and locations

Last reviewed version: 2.16

This information is mostly for system administrators who wish to know more about the installation of the AquaSim package.

Installed file locations

The AquaSim package installs to files to 3 locations, and writes to one subtree in the registry.

Program Files

The main program installs to {%PROGRAMFILES%\aquastructures\aquasim}. This includes all files required to run the main applications (AquaEdit, AquaView, AquaSim solver enginge, and post processing tools).

The application will need to be able to write to the file license.bin and to download and install the licensed AquaSim solver. The latter can be circumvented by manually downloading the solver through the license email, but license.bin will require write permissions. Downloading the solver through AquaEdit (Help -> Check for updated solver) will bring up a privilege escalation screen in order to copy the solver file to the program files folder.

The applications also write some log files (aquaedit.log, aquaedit_error.log, aquaview.log, aquaview_error.log, aquatool.log, aquatool_error.log). If the programs cannot write to these files some logging will be missing, but it is not neccessary to run the applications.

User documents folder

The AquaSim package installer will assume it can write to {%HOMEPATH%\Documents\Aquasim}. In this folder it will install some demo files, 3D shape files, and folders for storing files for the Library functionality.

If the users Documents folder is in a different location or for any other reason cannot be written to, please contact support for a version that skips the files in the Documents folder.


From 2.16 and onwards most programs will put their log files in %LOCALAPPDATA%\AquaSim. For better compatibility with restricted systems we will be moving more files to this directory in the future.

During installation

During installation the installer will install 3 redistributables silently:

  • w_fcompxe_redist_intel64_2015.0.108.msi
    • Fortran 2015 redistributable from Intel
  • cplusplus_redist.exe
    • Microsoft Visual C++ 2015 Redistributable (x64) - 14.0.24123
  • cplusplus_redist_2013.exe
    • Microsoft Visual C++ 2013 Redistributable (x64) - 12.0.40660

Fortran error, Ordinal not found

If the error “The ordinal 747 could not be located in the dynamic link library {path}” is displayed when trying to run an analysis first try to restart the system to make sure the path for the Fortran redistributable has been updated.

If this error persists after reboot try installing fortran_redist.msi found in %PROGRAMFILES%\aquastructures\aquasim\ and reboot. This usually fixes this issue.
