All installed extensions became local, and cant instal new ones. URI error. What's happened?

Recently you received an email with suggestion to upgrade your outdated Wealth-Lab Developer "6.9.15" to a more recent "6.9.15" build. Please follow the procedure in the email, in the Wiki (Errors | Extensions) or below, copied for your convenience:

If installation or update of a Wealth-Lab Extension results in a "URI Error" message with the error text "Error when identifying Extension download URIs...", we recommend you perform a reinstallation (which will NOT affect your Strategies, data and preferences) to solve the problem:

1. Uninstall WLD

2. Delete these folders with all the files (but back up your custom-built DLLs if you have them)
"c:\Program Files\MS123\Wealth-Lab Developer 6"
"c:\Program Files (x86)\MS123\Wealth-Lab Developer 6"

3. Download and install the updated WLD installer(s) from our website:

4. Reinstall all required Extensions from our website

Thank you.

Glad to help you.
