I've never heard of that tool before, but I'll definitely keep that handy in case anyone else runs into similar problems. Glad to hear you were able to get it sorted :)

To answer your question, you can use the "Ignore Monitors" option in the Advanced Settings. Just enter the monitor ID of the one you don't want the "Move to Next Monitor" button to apply to.

Thanks! ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#29 Thu, 16 Jul 2015 13:41:35 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#29 DisplayFusion Team - Success!

From all your help and information, I was thinking that there was a system/file/process security or related issue still on my laptop. For kicks, I used Windows Repair v3.2.5 (by Tweaking.com), and repairing the Policies Set By Infections and Restore UAC...I have all functions back.

Cool!

Hope this helps provide a clue should someone else have this issue in the future.

Thanks all again for the support.

Now...unrelated...how to I make the "Move Window to Next Window" button only togle between two monitors though I and using three monitors?

I terminated DisplayFusion, however the service was still running.
Then one at a time with a few seconds inbetween, I double clicked on:
DisplayFusionHookAppWIN5032
DisplayFusionHookAppWIN5064
DisplayFusionHookAppWIN6032
DisplayFusionHookAppWIN6064

Thanks man! ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#25 Tue, 14 Jul 2015 19:08:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#25 DisplayFusion The Process Monitor log shows that DisplayFusion.exe is trying to start the HookApp processes, but the HookApp exe's themselves don't show up in the log, which is consistent with what the DisplayFusion log was showing (Windows just outright rejecting the call to start them for some reason).

Could you try capturing another Process Monitor log, where you try to manually launch the HookApp exe's from the DisplayFusion directory? ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#24 Mon, 13 Jul 2015 22:08:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#24 DisplayFusion Roger: My limited Windows programming experience doesn't uncover anything in there, but maybe Keith and the engineers over yonder will take a look and see something I can't. If nothing else, the log should help to indicate how far the app got before bailing.

The 'buffer overflow', though, is just part of the app finding the correct buffer size for that query. It's just an error condition where the app is informed that it needs a bigger buffer and should try again with one. It's not to be confused with the 'buffer overrun' threats we all know so well.

I'll leave the rest to Keith et al. :) ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#23 Mon, 13 Jul 2015 15:10:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#23 DisplayFusion Thanks much all.

Kieth -
Older version installed at root is same same.
FileSeek Pro seems to function. Can access its settings.

Aiken -
Appreciate the advice, and executed your suggestion.
Attached is the Process Monitor dump when starting Display Fusion.
It is filtered for events where process name contains "fusion".
I started reviewing, found some buffer overflows and such, but honestly not sure that I am seeing any smoking gun.
Care to give a look?

If an admin, especially one working with his own credentials, rearranged or rebuilt some of the disk or registry hierarchy while fixing your machine, it is possible that he accidentally took ownership and left you with only read-only (or less) permissions to those items. I've done this to myself a couple of times and it took me weeks to work out what I'd done.

I'd suggest running ProcessMonitor from SysInternals, setting the filter to report just the app you can't get running, and see what (if any) activity it engages in before exiting prematurely. You may find, for instance, that it is trying to open some registry key for modification, or likewise some file on your drive, right before it throws its hands in the air and bails. Then at least you've got a lead and you can go sleuthing into file/key permissions.

The other thing that comes to mind is a modified PATH variable in your environment. You may be picking up some other app's version of a support DLL, or perhaps not finding one you need. ProcessMonitor would probably show that as well, since the DLL file should be sought before bailing.

File permissions shouldn't be an issue, but you could try installing DisplayFusion outside of the Program Files folder (maybe just C:\DisplayFusion) to see if that makes any difference. A few other things worth trying as well:

Run as Admin behaves the same - no Settings access, etc.

Unloaded OfficeScan, (Trend Micro), and still same same.

Are there any dependancies I could look into? For Example, if DisplayFusionHookAppWIN6064.exe requires admin access to a specific folder or files, I can check the security / permissions on those elements. I am just thinking that despite my PC being "fixed" by my IT, there may be some aspects of system or directory structure that DF requires that is only impacting DF.

Thoughts? ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#19 Tue, 07 Jul 2015 19:51:28 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#19 DisplayFusion Thanks! It gave a return code of -2, which I couldn't find much info on :(

I did find a couple of things while googling though. Would you be able to try these?
  • Right-click DisplayFusion.exe, and choose "Run as administrator"
  • Disable any security or antivirus software that might be blocking DisplayFusion from running, then try launching it again.

I will let you know as soon as 7.2 Beta 8 is available so that you can grab a new log and send it over.

If you just need to enable the third monitor, you should be able to do it through the Windows Screen Resolution Settings. Just right-click the desktop, choose "Screen Resolution," then click monitor 3, and choose "Extend to this display" from the "Multiple Displays" drop-down. ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#15 Tue, 30 Jun 2015 14:31:39 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#15 DisplayFusion Hello Keith.

I was able to finally collect the Debug file for when I attempt to load the settings only.
Display Fusion is not running.
Executed the DisplayFusion Settings link.

Please see attached.
I am adding a third monitor, and cannot configure, so any support is appreciated.

Something is preventing those .exe's from launching for some reason :(

If you like, you can try opening the Settings and send me a new debug log so I can confirm that it's the same issue. ]]> RE: Strange second monitor behavior after registry fix https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#13 Thu, 11 Jun 2015 14:35:36 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/strange-second-monitor-behavior-after-registry-fix/?ID=a911ab97-8407-4c0a-9c77-a98031d07322#13 DisplayFusion Keith -
While waiting for Beta 8 so we can log why the hooks are not working, any thoughts as to why I can not modify the settings?
I am stuck with the monitor configurations that I have already defined, but can not add more or modify.

Any additional thoughts?
The DisplayFusionHookApp exes are not running / visible in the Task Manager.

I have uninstalled and reinstalled .NET, and am now running the latest version, 4.5.2.

Additional notes:
I have tested all other programs installed on the workstation, and all seem to work as expected.
Uninstalled DF 7.1
Reinstalled DF 5.1.1 - no change in behaior: Incorrect StartButton action; unable to access any settings
Added the maniffest files as directed. - no change in behavior
