Notes on Installing AQUATOX Release 3.2 under Windows 7, 8, 10 Operating Systems. Aquatox 3.2 is 64-bit OS compatible.

  1. If AQUATOX will exclusively be run using an “administrator” account, no additional changes need to be made.
  2. If AQUATOX will be run by a user with a “standard” account, full read and write privileges must be given to that user for the directory in which AQUATOX has been installed.
  3. An alternative to adding read and write privileges: is to install AQUATOX in a directory where the user already has read and write privileges. This is the best choice when installing AQUATOX in managed desktop systems.

Additional details on installation may be found in the AQUATOX Release 3.2 Installation Guide
