AutoCAD Based Listing (Ribbon/Toolbar/Location)

Button: Start Autolist Error Type: Failed to launch

Description:

"AutoLIST Failed!... Please run Listing CheckUps"

 

This message is shown when running the AutoLIST process, but checkups didn't find any errors AutoLIST Failed

Solutions:

1.
Cause:

Unsigned application is causing the issue.
Solution:

HydraCAD updates 57.09 and 58.03 should resolve the issue.
2.
Cause:

Outdated/unsigned application files
Solution:

Using Windows File Explorer, navigate to this folder and check the version of this file by right-clicking it, selecting Properties, and check the DETAILS value tab.

C:\HES\Common


DAO32Server.exe

It should be file version 2026.04.30.32 or newer.  

If you have an older version, please close all Hydratec products and download and run this install:

Hydra_DAO_Install

It updates these two files and creates a windows service called Dao32Server;

DAO32Server.exe

Dao32Server.tlb
3.
Cause:

1) Bad VP lengths in a Metric drawing

 

2) Grid has user defined RNs on both ends.

 

3) Fitting that does not exist. Ex. Head on a tee creating a 4 outlet fitting.
Solution:

The length of the VP was 6mm and checkups didn't catch it as an error. A length of 6" is fine for Imperial, but in Metric, it's too small for AutoLIST to handle.

**IMPORTANT** If using HydraCAD 52.04 or older, you MUST close and re-open AutoCAD before running another AutoLIST as trying to run the process again will give a FATAL ERROR.
4.
Cause:

Bad install of HydraCAD, likely due to anti-virus blocking some HydraCAD install files [7/28/21 GAB]
Solution:

User was running Kaspersky.  Witnessed the install of HydraKEY, but then when we attempted to run it, Kaspersky blocked and DELETED the application.  Disabling Kaspersky and re-installing HydraCAD fixed the issue.
