Duplicacy don't open

After the update, the application on windows don’t open.
He’s open the process and close after that.

I don’t have more informations

Was there any error dialog? If you run Task Manager do you see the process named DuplicacyGUI64.exe or DuplicacyGUI32.exe?

No showing any error dialog. I cant find anymore the proccess in Task Manager. I dont know what is happening…

I would suggest a complete reinstallation. Remove the registry key HKCU\Software\Duplicacy and HKLM\Software\Duplicacy before reinstallation.

i have made this steps and nothing change… keep not working

Bunch of questions to narrow down:

  1. Do you run installer as Administrator (or as restricted user)?
  2. If yes, do you install it for the current user or for all users?
  3. If for all, do you set it up as a service?
  4. Is it possible you ended up with two installations (one for all users and the other for local user?)
  5. When you uninstall, do you run uninstaller as administrator? (Otherwise is silently does nothing <-- this is a bug btw)
  6. what happens if you start duplicacy as Administrator (as opposed to restricted user)?
  7. What happens if you temporarily disable UAC (Start menu, search UAC, enter, drag slider all the way down), reboot and try to launch it again?
  8. What version of windows does it occur on?
  9. Which version of duplicacy worked and which one does not?
  10. What happens if you run executable directly from %APPDATA% or from Program Files (as opposed to using shortcuts from the start menu)?
  11. Do you have any security solution installed such as mcAfee antivirus? Did it report anything? Have you tried disabling it and trying to relaunch?( could be false positive)
  12. What happens if you open command line (search CMD, right click and start it as Administrator, cd to the installation folder and start the exe file. Do you see any errors reported?

Radical steps (if you have spare time)

  1. Install WinDBG Preview from Windows Store and install Duplicacy as a restricted user.
  2. Start windbg and go File -> Launch Executable.
  3. Navigate to the location of DuplicacyGUI64 and select it. It will be in C:\Users\me\AppData\Local\Duplicacy
  4. In the edit box in the middle of the screen type gh and press enter (cursor should already be there).
  5. Duplicacy should start. It shall appear or it shall be available in the task bar icon area)
  6. If it does not, debugger’s “command” window above will contain some useful information. Share it with us.

I use Windows 10 Pro 64 bits.
I have made all this steps except the Radical steps, and executing the DuplicacyGUI64.exe from cmd works, but from click not working…

I have tryed the WinDBG and make the steps and GUI not opened, just the thread.
The output from WinDBG:

So, the problem must with with the shortcut then. Perhaps the “Start in” directory has changed?

Can you create a new shortcut to it on the desktop and see if that works?

I create a new shortcut and still not working

I create a new shortcut and still not working

Wow. That does not make sense.

So, when you double-click the shortcut nothing happens, and if you look in the tray area there is no duplicacy icon? And the “Start in” directory is the same as the location of the executable in the shortcut properties?

Did you use WinDBG from SDK or WinDBG Preview from the store? How did you load the executable?

Anyway, disregard that - because you have confirmed that starting the executable directly works, so the problem is not with Duplicacacy.

I use the Preview version of WinDBG. I m installing the SDK version now.
When i double click in the shorcut nothing happened… And in the executable too. Just from CMD works.
Its the same location the executable from where i start from CMD.

Well… If i install for all users (as a service), its works!!! If its only for me, not working… I really dont know what is happened.

There is no need to install WInDBG from SDK, the one from the store should have worked fine, but apparently it is also failed for you. Did you follow the steps exactly?

This all does not make sense, unless you have some weird shell extensions installed that screws your explorer. Does other applications start from shortcuts?

Try two things.

  1. You have already confirm that launching the app by name from cmd works. Can you try now launching it using “start” utility? ie. start DuplicacyGUI64.exe as opposed to DuplicacyGUI64.exe
    Does it still start?

  2. Boot into safe mode. Does it start there from a shortcut?

Well… If i install for all users (as a service), its works!!! If its only for me, not working… I really dont know what is happened.

Did you uninstall the instance for “all users” before installing one for yourself and confirmed that it was uninstalled?

Still does not make sense why shortcut would not work.
