unable to load dbcapi.dll

[eparks]

I get the message: unable to load dbcapi.dll

... when IB TWS is loading and trying to connect to esignal as the data provider.

Is this a permissions thing?

epark,

We've seen it a couple of times and the same fixes doesn't work for each user computer. It's a hit or miss with the Windows 7 (64 bit) machines. Make sure the following things are configured as shown below. Once the settings are done it may required that you reinstall TWS again.

1- The user account should be a part of the admin group
2- Turn off the UAC (Control Panel-->User Accounts)
3- Run eSignal and TWS as Administrator(Right click-->compatibility)


There is one other options, If you user the Internet Version of TWS where you log in from the IB website. The error has not come up there.

Let me know if which if either of these works for you.
