AutoCAD 2020 integration issue

 I recently upgraded from AutoCAD C3D 2019 to 2020. I left C3D 2019 on my machine. The WTRCRUN command is unhandled in the 2020 version. I kept the 2019 installed and watercad will run normal in it, but will not open the cuix files or run any wtr commands in C3D 2020. 
 Am I missing an integration update possibly? 
 Ref: 
 I installed WCAD 10.02.01.06. 
 OS: Win10 
 GC: NVIDIA Quadro K2200 (updated driver installed)

Hello Nic, 
 In my testing a fresh install of Civil3D 2020 and WaterCAD 10.02.01.06 appeared to work without an issue. I was able to open and compute a model. I also compared the acad.exe.config file and it was essentially identical to yours. 
 However, I was able to reproduce the "unhandled exception" error one time, by purposely closing out of the CONNECTION Client. The CONNECTION Client is used by WaterCAD in order to license the product. However, when trying to reproduce the issue again, I was not able to - the CONNECTION Client automatically started, as expected. So, I suspect that the CONNECTION Client may somehow be related to your issue, though I am not certain exactly what condition causes this. 
 Please first check if you have the CONNECTION Client open and are signed in. It might be best to start by opening the Standalone version of WaterCAD, which should automatically open and present the sign in screen. If you find that the CONNECTION Client is still not opening, please try reinstalling it (it is included with the WaterCAD installation, and can also be downloaded separately). See more troubleshooting tips for CONNECTION Client issues here . 
 
 Also, once confirmed that you are signed into the CONNECTION Client, check that your WaterCAD is properly licensed. Open the "Feature Level Selector" from your Start menu and ensure that the selected Feature Level includes "AutoCAD" in the list of features. Before opening the AutoCAD integrated mode, ensure that Standalone WaterCAD is working. Try opening it then check under File > Help > About to see if the license status is OK. Also, try opening and computing a model. 
 Lastly, see my previous reply regarding CAD functionality in the Standalone version that you might find useful.

Also, I have now added a note about the CONNECTION Client in the following articles in our Wiki:

Hello Mohamed, 
 This link has information on the error. The first item mentions to be logged in to the CONNECTION Client, so you will want to make sure that you are doing this. 
 If you are and the issue still occurs, try reintegrating WaterGEMS and AutoCAD. You can do this by closing both programs and opening the Control Panel. Go to Programs and Features, highlight WaterGEMS, and select Uninstall. When you do this, a dialog will open giving you an option to Repair. Select the Repair option. 
 If that doesn't help, the link above has additional steps you can try. 
 Regards, 
 Scott

Hi Nic, 
 Good news - we were able to locate a fix and have documented it here: 
 Unhandled Exception - eo434352 (eo434352h) when working integrated with AutoCAD 2020 
 It involves adding a few lines to the top of the acad.exe.config file from the AutoCAD installation folder. We are still unsure why AutoCAD 2020 integration worked previously without this and does not appear to be related to either Windows/.NET updates or Autodesk updates. We are about to release a new version of our products (10.03.XX.XX) and will plan to add these lines before we release. 
 Please let us know if you run into any trouble applying the fix and please confirm that it works for you.

Hello Nic, while we look into this (I am trying to set things up to test this), could you tell us a little about how you use WaterCAD with AutoCAD? There are many tools and features available in the Standalone version that might be used as a workaround/alternative to AutoCAD integration (as an interim solution so you can proceed). See from our Wiki: 
 CAD Functionality in Standalone as an Alternative to AutoCAD or MicroStation Integration

Thanks for the update, Nic. I'm glad to hear that it is working now. 
 Regarding automatic sign-in for the CONNECTION Client - click the gear icon, choose Preferences, then check the boxes for "automatically sign me in". See more in this article: Preferences

Regarding "fatal error" - in my testing, I encountered this (with the CONNECTION Client closed - now I cannot reproduce): 
 
 I see now that it is slightly different from the exception you encountered (as seen in the video you had previously uploaded) - 
 
 I have amended the article as I believe these are likely variations of some of the same underlying issues.

Hello Mohamed, 
 I would have CONNECTION Client open and be logged in before you open WaterCAD for AutoCAD. If that is not the issue, please provide further details on the issue.

Hello Nic, 
 We have received several other reports very recently of similar issues and so far the problem seems to point to Autodesk. Is this the exact wording you're seeing? - 
 
 Unhandled Exception - eo434352 (eo434352h) when working integrated with AutoCAD 2020 
 Please check your installed updates to see which ones were installed between when the integration was working and when it stopped working. This is located in Control Panel > Programs and Features > View installed Updates. 
 You mentioned you tried reinstallation - did that include fully uninstalling and reinstalling AutoCAD? 
 Lastly, please note that the Standalone version of WaterCAD has the ability to work with and produce CAD files and may suit you needs: CAD Functionality in Standalone as an Alternative to AutoCAD or MicroStation Integration
