Error or Warning Message

When I start my standalone software I get an error message that says "Failed to load managed assemblies". When I start my WaterCAD/WaterGEMS for AutoCAD software I get an error message that says, "Unhandled exception E0434352 (e0434352h) at address FD67940Dh" and it mentions the path "C:\Program Files(x 86)\Bentley\WaterCAD\x64\wtrc1964.arx" at the top of the dialog box.

Explanation

You may have a bad install the requires an uninstall reinstall of the software.

How to Resolve

  1. Uninstall WaterCAD or WaterGEMS using the control panel > programs and features > uninstall option
  2. Download a new copy of the install file from the Bentley Website and save it on your local hard drive.
  3. Right click on the install file and choose the "Run as Administrator" option. This should ensure that everything is being installed properly because it's being installed with full administrative privileges.
  4. Download the latest patch set for the software and then repeat step 3 to also run it as an administrator.

Other possible solutions to the issue include:

Browse to C:\Program Files (x86)\Bentley\(program name) or C:\Program Files (x86)\Bentley\(program name)\x64. Find the application file to launch the program. For WaterGEMS, this will be called WaterGEMS.exe. Try launching the program from here. If it works, try making a new shortcut for the file. 

The issue may be also related to the installation of .NET 3.5. WaterGEMS and WaterCAD uses this during installation and calculation. If it is missing or corrupted, it can sometimes cause issues with the use of the product. .NET 3.5 is a part of the Windows 7 operating system, and may not be present in the "Programs and Features" section of the Control Panel.

You may need to get some assistance from IT, but you will want to verify that .NET 3.5 is there. You can reinstall .NET 3.5 and .NET 3.5 SP1. After downloading and installing these, reinstall WaterCAD to see if that helped.
