"As a past ******* customer(and not a happy one), IQ Feed by DTN is a much better and cheaper product with great customer support. I have had no problems at all since switching over." - Comment from Public Forum
"The people at Nirvana have very nice things to say about your company and I can see why! Price and service is a potent combination." - Comment from Ed
"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 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
"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John
"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam
"I am very happy I changed. I love the product, but more so I am thrilled with Tech Support. You are knowledgeable, polite, pleasant and professional." - Comment from Pat

DTN.IQ Client Software Support » IQfeed installs but won't run (Windows 11) Jan 12, 2023 02:57 AM (Total replies: 4)

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.

DTN.IQ Client Software Support » IQfeed installs but won't run (Windows 11) Jan 11, 2023 06:48 PM (Total replies: 4)

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.
