Calibre not opening after update to 5.0 - Page 2

AgCOtter · 09-25-2020, 07:09 PM

Good Evening,

I am not able to install 5.0.1. at this time. I started the first install and after checking the permission box and the install box the process started. Started to copy new files and then stopped, displaying the message on the right. When all is said and done the message on the right pops up.

I have deleted the program Calibre, uninstalled C:\\Program Files\\Calibre2\ and attempted to reinstall calibre. I have rebooted after the second attempt to reinstall and I get the same message. I would appreciate any suggestions. Please let me know what information I need to provide to assist in clearing up this matter.

Intel(R) Core(TM) i7-1770K CPU @ 3.50GHz
32.0 GB Installed RAM
64-bit operating system, x64-based processor
Windows 10 Pro
Version 2004
OS Build 19041.058
Windows Feature Experience Pack 120.2212.310

Thank you.

The 5.x MSIs have some weird issue.

I have absolutely no clue what that could be. The MSI generation code has absolutely no changes between 4.x and 5.x.

Hi Kovid,

I'm running Zorin Linux, and have been on Calibre 4.x. I missed the jump to 5.0, but when I upgraded to 5.0.1 and tried running it, I got the following error message:

Quote:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted

I tried re-installing, but had no joy- I still got the same error message.

Any ideas?

@Immelman you are missing one of Qt's dependencies, probably libxcb-xinerama0

Immelmann67 · 09-26-2020, 10:22 AM

Thank you for the quick response- I'll have a go at that. It wasn't necessary before- is it a new addition?

Not to calibre, but to Qt which was also updated as part of calibre 5.

Immelmann67 · 09-26-2020, 10:47 AM

Well, the suggestion worked, so I'm back up and running. Thank you!

AgCOtter · 09-26-2020, 11:48 AM

Good Morning,

Appreciate your response to my issue. I removed power toys and ran the install. I got the attached message from the process. So I followed your original instructions of:

"Uninstall, delete C:\\Program Files\\Calibre2
(or wherever you chose to install calibre). Then re-install. And
don't worry, uninstalling will not affect your books/settings."

I added a reboot just for good measure, and success

You guys and gals rock.

Tried installing on win 10 enterprise and it failed,
exited power toys, then install succeeded

Just dump the awful PowerToys. Don't just exit. But delete them and never look back.

Snodgrass · 10-02-2020, 01:57 AM

Brilliant. 5.0.1 cured the problem.

Thank you muchly.

Err...but why? The PowerToys are useful.

They may be useful but some of the side effects are a total PITA. I play with them in a VM (currently 0.23.0 is installed). The only, to me, really useful toy is the Rename utility. PT Run may no longer interfere with installs but still crashes far too often for my liking. FancyZones, Keyboard Manager, etc. are meh. The Video Conference utility which sounded interesting due to the amount of time I'm spending in them these days has been put off again. The version in the beta 0.22.0 was not ready for prime time though what it did to Teams was fun for certain peculiar senses of humour's definition of fun.

Way back when in the early days of PowerToys, they were useful. Now they just get in the way and cause all kinds of problems.
