Hello,

I have forwarded your report to the Stardock support team for their review and recommendations.

Please keep an eye on this thread for any updates.

We really do appreciate your feedback, thanks.

Thanks, Sean, I'll try to answer these in order:

1) Has it ever worked to KVM connect tot he PC in question? -- No, this is a new purchase, and this is the only time these two computers have ever communicated via Multiplicity

2) If you disable the firewalls on each PC, does that have an effect? -- Good question, I'll have to look at what firewalls each PC, but to the best of my understanding, the only firewalls are those built-ion to Windows 10.  Does it help to know that "Seamless" works fine in the current state?

3) If you redo the connection and add it by IP (type it in), does that change the result -- Per the Connection 101 instructions, I tried using the IP address after it didn't work the first few times, no better.  This was before I did the full purge and reinstall.  I haven't tried using the IP afterwards, as the instructions indicated to use all defaults.  Both computers are on the same 10.0.0 subnet.

4) Do you connect to others that do work? -- I haven't tried yet, but if you think this will result in better troubleshooting information, I can try.

5) If you try the opposite, make the Secondary a Primary, reversion the current Primary, can you connect to it? -- Also a good question.  Can I use the same license code on two computers (the one I _want_ to have as Primary, and the one I'm wanting as Secondary) without trouble?

6) Is the Secondary headless (no monitor)? -- The secondary does currently have a monitor, but only because I'm trying to get it working headless, and I'm borrowing the monitor from another workstation.  Could the fact that the Secondary currently has a monitor be fouling the KVM connection somehow?

7) Do you have 3.5 installed on each PC? -- Exactly the same version is running on both machines, as per the About, although the Secondary reports "Version 3.5 Build 00096" and the Primary reports "Version 3.5 Build 00096.kvm".  Both versions were downloaded from the same link (Download)

Hello,

For the time being, we want any test PCs to have monitors attached.

If it is indeed 'crashing', is anything showing in the Windows Event viewer on either the Primary or Secondary?

Does anything show for connections there if this is enabled on the Secondary:

Does the Secondary has 2 video cards - one integrated perhaps?

Is it at all possible to share a link to a video of the whole process (shared linked to Google Drive, OneDrive, DropBox, etc)?

I turned on the Logging to the Event Log on the secondary, and although I see some other Informational stuff in the Application Log, the only one I see directly relating to Multiplicity is:

The description for Event ID 257 from source Multiplicity cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

KVM connection initiated by 10.0.0.204, internal port: 18049

Thank you for the information.

What we would like to do is see that it is not a 3rd party app conflict.  While laborious, the most effective way to do this is a clean boot:

Again, this would need to be done on each box.

We would also like the exact OS builds for each box (winver.exe).

Thank you for your time, effort, and patience.

Can you RDP to the 2nd PC?

Having the same problem evaluating Multiplicity V3.5, ie secondary computers apparently connecting but not opening a desktop on the primary computer. 

After uninstalling and purging V3.5 then installing V3.44 was able to connect to the secondary computer immediately without any problems.  They are both running Windows 10 home 2004 build 19041.450 with Norton Security.  They are also on the same subnet, one connecting via ethernet and one on wifi.

I have Multipplicy Pro 3.5 Build 00096.kvmpro, installed on 6 computers (5 Windows 10 Pro, 2004; 1 Server 2016).  One of the WIn 10 machines is primary; all others are secondary.   The program works perfectly on 4 of the 5 secondary machines.

The 5th machine is another story.  I can connect to it and I can send it a Ctrl+Alr+Del, to which the machine responds aw well as to any other keystrokes such as entering a password following the three-key salute.  However, there is nothing displayed on the primary computer, the screen remains blank.  

I have removed Multiplicity from the computer, removed it from the list of computers on the primary computer, and then installed the software and added it back into the list of computers on the primary machine.   All this has made no difference at all.

The computer in question is an HP Z-Book 15 G3 (a laptop), i7-6700HQ, 16 GB RAM and 369 GB of free disk space.  All drivers are up to date per HP's softpaq manager.   It has two onboard/built-in video cards, an Intel HD Graphics 530 and an Nvidia Quadro M1000M.   No external monitors now or ever.

I have found this problem goes away if I change the BIOS to use only the Nvidia "card".    This is not a fix because I lose the power savings of the machine using the Intel "card" for undemanding/light display tasks.

I had this same problem with the previous release of Multiplicity (3.44) and hoped it would be resolved with 3.5.  No such luck.

Thank you.

The program IS installed in C:\Program Files (x86)\Stardock\Multiplicity on both computers

I do not - and never have had - any problems with the program crashing on either computer. 

This is why this thread is NOT appropriate for my issue.

So where does this leave this issue?   I have answered your questions and tried that file - which made no difference.

I certainly understand that crashing has to be the priority but I don't have crashes, just a blank screen. 

By way of reminder, I have an HP Zbook G3 laptop.  The machine has Intel 530 graphics built-in as well as a discrete Nvidia Quadro M1000M.  In its two of the three graphics settings in the BIOS (auto and hybrid), the machine apparently uses the Intel sometimes and sometimes the Nvidia.  It does this automatically and transparently and there is no external monitor involved.   Both the Intel 530 and Nvidia M1000M show up in Device Manager.  

However, this seems to befuddle Multiplicity.  With either of these BIOS graphics settings, I can connect to the laptop from my primary computer without any problems and the laptop responds correctly to any inputs from the primary (Ctrl+Alt+Del; typing in a password; etc.).   Unfortunately, the window on the primary computer where I should see the ZBook's screen remains blank.   There are no crashes on either machine and the primary computer can connect to the other secondary machines (4 of them) with no problem.

If I set the Zbook BIOS graphics option to Discrete, everything works perfectly.  Only the Nvidia M1000M shows up in Device Manager with this BIOS setting.
