HydroCAD® Stormwater Modeling - Since 1986


Windows Compatibility Information

What versions of Windows are supported?

HydroCAD-10 has been carefully designed according to Microsoft and industry standards so that a single program can be used on all versions of Windows, including Windows 98, ME, NT, XP, Vista, and Windows-7.

Earlier versions of HydroCAD (6.0-8.5) will also run under Vista and Windows-7, but you must install the 32-bit help system from Microsoft in order to enable the tutorial and context-sensitive help.  HydroCAD 9.0 avoids this problem by switching to HTML help, but the latest HydroCAD-10 release is recommended for all systems.  (See table below for details.)

How much memory does HydroCAD require?

Disk and RAM requirements are very modest.  Basically, any system that can run Windows will run HydroCAD.

What about 64-bit operating systems?

HydroCAD is fully compatible with 32-bit and 64-bit editions of all supported operating systems.  The same  installation program is used for all environments.

Security Considerations

HydroCAD 10.0 supports the use of secured computing environments in which the user has does not have write access to the HydroCAD installation folder.  All data files are stored in the designated Windows folders for application data and user data.

With HydroCAD 9.1 and earlier, each user must have full read/write access to the HydroCAD installation folder, which is normally C:\Program Files\HydroCAD.  To run HydroCAD on a PC that is fully secured, the administrator will need to provide read/write access to this folder and all subfolders.
