This page contains tips and solutions for common download problems.
Please read carefully, and your problem will be resolved in just a few minutes!
1) Where is the download page?
There are different download links for each edition of HydroCAD.
2) I can't access the download page
If you can't access the download page at all, make sure you used the correct

this page indicates that you have a connection to our web server, so the
download link should work as well.
3) My login name and password were rejected
Be sure you typed the information correctly. If you used
copy-and-paste from your download email, be sure you haven't copied any extra
spaces. Be very careful to distinguish between any zeros (0) and ohs (o).

Make sure you're using an http connection not https.
Check you address bar and make sure it does not show https.

You may have a firewall or other restriction that blocks the download.
You will need to contact your system administrator about these problems.

Options" from the "Tools" menu, and then select "Delete Temporary Files.")

selected. Please click here for help with
