API-DDE hangs up

This morning, my Interactive Brokers API-DDE hung up launching.

I tried everything, rebooting, running CCleaner, clearing Chrome history.  More rebooting.  Running only Excel and nothing else.

But nothing works.

    I gave up on DDE altogether, and switched to ActiveX.

    Make sure you didn't accidently launch the 64-bit version of TWS.

    It only works on the 32-bit version.

    If you want both versions on the computer, I find it best to install the "stand-alone" 32-bit version.

    It won't auto update, but installs to a separate folder, so one can also have the 64-bit version as well.

    Just make sure you launce the 32-bit version when working with Excel.

    Running only Excel and nothing else.

    If it's only Excel, and not running TWS at all, then I believe one needs the "IB Gateway" to be 32-bit as well.

    Make sure it wasn't updated by accident to 64-bit

    No changes, no error message (just a white screen).  I've had Bloomberg, Acrobat, and Avery Add-Ins for many years, and the DDE-API worked just fine.
