"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don

"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.

Author	Topic: IQfeed installs but won't run (Windows 11) (5 messages, Page 1 of 1)
jasonl -Interested User- Posts: 2 Joined: Jan 11, 2023	Posted: Jan 11, 2023 06:48 PM Msg. 1 of 5 Hello - I installed the IQfeed client on a 64-bit Windows 11 pro system, version 21H2. All Windows updates are current. IQfeed installs quickly and without any errors. I cannot see any obvious issues in the install log. But upon installation, I cannot start any of the IQ apps. The freestanding apps themselves won't pull up - no GUI. But I do see each app in the process table after double-clicking on each. It shows up in taskmgr, but no GUI. IQconnect.exe only shows up when you run diagnostics.exe and hit the 'test' button. Diagnostics stop at "register application' stage because the connection does not complete. IQconnect hangs at "received authorizations" stage. Logs show the server is reachable and it appears the creds are accepted. Of course, calling IQfeed through a trading platform has the same result - does not connect. There is no antivirus or other software running that could be stepping on anything. There are no issues with any other software, OS, drivers, broker or 3rd party data feed or trading platform on this machine. My DTN account is also fine because I can connect from another machine. Rebooted the system multiple times, uninstalled and reinstalled IQfeed multiple times, including deleting registry keys in between to remove all traces. Any help would be appreciated.

jasonl -Interested User- Posts: 2 Joined: Jan 11, 2023	Posted: Jan 12, 2023 02:57 AM Msg. 3 of 5 Good question. I do not. Attempting to start any IQ app from the command line immediately returns the command prompt without any errors or warnings, but interestingly, the apps do not start, or at least I can't find any evidence that they do. I tried with several. They're not in the process table. This is distinctly different from simply double-clicking the apps inside Program Files\DTN\IQFeed in which case you get the Windows wait cursor (the blue circle) for a couple of seconds and then the app appears in the process table but there is no GUI and no way to interact with it.
