Windows XP after fresh restart 3. Attempt to run "News Example" that ships with developer package (using Start->Programs->IQFeed->News Example) 4. Login page appears ... logs in correctly and THEN.... 5. An error dialog appears saying: "Error: A version of IQ Connect is already running" Exactly the same problem with ANY OTHER application using IQFeed including IQFeed's own apps: History, Watch List, etc as well as 3rd party apps: QuoteTracker, my own app (amibroker). The only way to get rid of it is to perform FULL WINDOWS RESTART. And then sometimes one restart helps sometimes not. This status quo is for more than one year (yes I reported it earlier directly to IQFeed support).

Could you verify the location of IQConnect, based on the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\DTN\IQFeed\EXEDIR If the IQ32.dll used by your program isn't the same one used by IQConnect, this error always happens. Is this a situation where no programs will run or only one? Glenn Benes Glenn Benes DTN Market Access, LLC.
