Can’t connect MyMobiler due to a busy ActiveSync connection

I installed MyMobiler on my computer, but couldn’t connect to my HTC HD2. The exact words in the message has slipped my mind, but it said something about an ActiveSync connection being busy.

In my case, that message was both unhelpful and totally wrong. The real reason was missing drivers on my Windows 7 64-bit system:

1. Download and install the drivers.
2. Reconnect the phone, make sure to select the ActiveSync option.
3. Wait for the driver to complete the install.
4. Exit MyMobiler and start it again.
