Cockatrice: Error opening Qt5Core.dll for writing during installation

[pdm619]

Windows 7 Pro. Never had Trice on this laptop in the past. Won't get passed here. Any help?

[Daenyth]

Does the "Cockatrice" folder in program files exist? If so, try deleting it and running the installer again.

If that doesn't help, try running the Qt4 version instead - it's listed on the download page as the option for windows XP/Vista.

This isn't the first time I've seen this. At least 5 people have come to me privately to ask, yet none ever did open a ticket. I believe it was fixed by reinstalling the QT library

[pdm619]

This is what I get with that file

[pdm619]

How do I reinstall the QT library?

[Daenyth]

@ZeldaZach do you mean the vc redist? I thought our installer bundled the qt dll

This error would be caused by 1 of 2 scenario's. The first is the file is in use. To resolve the in use issue close the app before trying to uninstall it and if you still have the issue reboot your PC as there is something retaining a file lock to the file. The 2nd issue would be permissions based. Verify you have permissions to install to that folder, you may need to run the installer as administrator depending on your windows settings.

@woogerboy21 OP said the he has _not_ had trice on this machine before

[woogerboy21]

Chances are he has his DEP settings or something set to a level that requires higher permission to be installed. In windows you shift+right click on the program installer file and choose "Run as administrator".

And for the clients that have Windows 7 but the Qt5 version doesnt run on, it throws some error about can't inject something something DLL file (its very cryptic) and those are the ones that would need to run the Qt4 version of the client. It happens on certain older processors that are missing some microcode and I believe are only AMD based processors if I recall.

Tried everything above and it wont install. Ran as admin and everything. Same error

Your not out of disk space are you?

Possibilities, from the most to the least probable:

1. missing permissions: ensure you have administrator rights, right click => run as administrator;
2. trying to overwrite a locked file: ensure no cockatrice is running, if needed reboot the pc;
3. some problem on the filesystem: scan the disk for errors (chkdsk, needs a reboot);
4. corrupt installer: redownload the setup;

As a test, you could try to manually create a file named after the filename you receive on the error and see if it works.

412gb available. I run as admin no problem.

[pdm619]

Still the same error. Bummer.

[tooomm]

did you try explicitly to install with this file yet?

just making sure...

Antivirus maybe?

@pdm619 did you manage to get your problem solved? We have a similar report from another user, it would be nice to know your solution if any.

Have the same problem, fresh windows 10. Run setup as Administrator after reboot and get this issue.

[tooomm]

Which version do you try to install? Where did you download it from? @dekmabot

Do you use any antivir software? Can you try disabling it during install?

Version 1.14.50.37, downloaded from jetbrains.com todays morning. I have no antivirus software, so nothing to disable, its a new official windows install.

By the way, I tried to setup it several times (with reboots, as administrator), and it fails each time with the same error. But some time later, after cold reboot it just starts automatically and now works perfect. Don`t know, maybe it fails with error AFTER it installs properly?

[tooomm]

You are in the Cockatrice repository, I think you are talking about a different software?

Oh, please forgive me, fluent googling have fooled me!
Thank you for your responces anyway =))))

I ended up with this problem while trying to install a JetBrains product. Here's how I solved the problem:

• The installer gave me the path to the QT5Core.dll that it was having issues with, which was deep within my AppData/Local folder
• I tried to delete the entire JetBrains folder that contained this file, which turned out to be non-trivial because it said a file in it was open

• I opened ResourceMonitor and found that the jetbrains installer executable was still running (2 .exe's actually)

• I killed these two processes
• I then deleted every JetBrains folder within AppData, which was successful after the processes had been killed
• I rebooted, redownloaded the installer, and everything went smoothly the second time

Hope this helps
