When opening HydraCALC SIZER, you get the error;  Run-time error '53': File not found

When closing a drawing in 3D, and later re-opening and returning to 2D, some of the drawing symbols show up looking like outlines (Hangers, Sprinklers, etc)

When opening HydraCAD, you get the error message saying, "The Ribbon does not have any tabs or panels currently loaded"

Error appears when opening Hangers

Failed to load the following families: z_Pipe Elevation Marker

After opening AutoCAD and a drawing, you have a dead area where you can't draw nor does anything display.  Usually next to a compressed palette.  Note in the image below how the crosshairs do not extend to this area.

When opening HydraCAD, you get this error

Unhandled Exception...DAO32Server...

Trying to open Listable Dynamic Blocks and you get this error message

The problem is, you already have a newer version. 

Go to HydraLIST, click [Help|About HydraLIST] to confirm.

Valve selector unable to open in Revit Beta Ver 25.1.003

While using the 'Choose Part Number' button to open HydraHEAD Selector and retrieive its description and part number, you get the errors below;

Runtime Error 713, Application-defined or object-defined error

Sprinkler not properly configured.  Please re-select using 'Choose part'

When starting the AutoLIST process, the message box shown below pops up.  The process "pretends" to continue through, but when HydraLIST opens, it's completely blank.

When opening HydraCAD, you only receive this error message and not a HydraKEY error with the golden X.  If you receive a HydraKEY error, search for the linked HydraCARD in that message box as it takes priority.

Security Error:  One of the following conditions is likely;

HydraCAD is unable to function under these conditions

• Lock database needs updating in HydraKEY
• Accounting flag on your account
• Hardware lock not plugged in
• Extra ACAD.RX file found in folder in Support File Search Path
• Sentinel driver is missing
• InstallPath registry item set to wrong drive

After AutoCAD opens, press F2 to view the command prompt, see if the text below appears.  If yes, see solution 1.

After buiding your 3D risers, raising to 3D, exporting to a Persistent Model and Navisworks successfully, your 3D riser is missing, with the exception of the skipoles

Your layers are on and the 3D_DETAIL layer is present, unlocked, thawed and visible, you just can't see the pipe and fittings.  The one customer reporting this said they disappear if the drawing is closed then re-opened.  They'll be visible in viewports as well, just not in 2D view.

During the install of HydraCAD V56/57/58, the user is greeted with the message below.  Following the both sets of instructions of opening and closing AutoCAD, and running a repair of AutoCAD do not make a difference.  You'll still get the error message.

V56 = R23.X
V57 = R24.X
V58 = R25.X

V57 install will say;

Neither AutoCAD 2021, 2022, 2023 nor 2024 found (missing registry key:

HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R24.X).

Please install it before re-running this install
