Eugene,

Where in WLD to save DLLs generated from Visual Studio for debugging purpose? With WLP, I have the DLLs saved to the folder "C:\Program Files\Fidelity Investments\Wealth-Lab Pro 6" and WLP can find it, when clicked on "Open Strategy" icon of WLP. However, with WLD, the mentioned steps does not work. Thanks.

1. Right click VS and "Run as Administrator"
2. In VS, select Debug Mode.
3. Open the project's Properties and click on the Build item
4. Point the Output section to C:\Program Files\MS123\Wealth-Lab Developer 6
5. Close Wealth-Lab
6. Build (F6). Your dll will be added to the folder in step 4. If the Build fails, make sure you did steps 1 and 5.
7. Start Wealth-Lab

Made a couple of edits and updated paths in the KB article:

How can I debug my trading strategies in Wealth-Lab?

Thank you Cone and Eugene.

I followed the steps from Cone on post #2 and the dll was added to the folder and loaded into WLD correctly. However, when WLD re-start, it crashes within 1 minute. WLD keep crashing after I try to re-start it multiple times.

During the 1st re-starting of WLD right after the build, I was prompted to update several extensions. I am now not sure if the crash was caused by that from post #2 or from those extensions that just being updated or from something else. Is there a log file contains information about the WLD crash that I can look at? Thanks.

1. Repair your WLD installation from Windows Control Panel > Programs. It's advisable to delete all files in the installation folder since you're a developer.

2. After that, open your project in VS. In the References section of your project, review all Wealth-Lab DLLs referenced and change every one of them that points to your Wealth-Lab Pro installation folder, to the same DLL file in WL Developer folder. Namely WealthLab.dll which appears to be copied over from WLP. Doing so will cause the crash within 1 minute.

That works. I might have spot something like this if not rush to get WLD working. Thanks Eugene.

Glad to see you're up and running again!
