Installer: failed to start because no Qt platform plugin could be initialized
maphew opened this issue · comments
When running the 64 bit installer for maphew appveyor dev release (fake v1.0.30) at the end regsvr32 reports "This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem."
Followed by:
Error
C:\Program Files\Dotz Softwares\SVG Explorer Extension\SVGThumbnailExtension.dll
Unable to register the DLL/OCX: RegSvr32 failed with exit code 0xC0000409.
Click Retry to try again, Ignore to proceed anyway (not recommended), or Abort to cancel installation.
Win10 Enterprise 1803 build 17134.1130
After running install program and choosing [ignore], browsing to a folder with .svg files in it, the "failed to start" error dialog reappears, and naturally there are no previews:
This is a different machine from the opening post, and using an installer from today.
This is a Qt thing. Some platform code is implemented in plugins. These have to be shipped with the installer and QCoreApplication has to be able to find them.
Once I got my dev environment running it should be simply to identify what doesn't like.
#45 should fix this issue.
Check in Initialize method in Main.cpp.
Getting this message still with the real v1.0 release. After the regsvr32 Qt plugin error there's a new one, "Unable to register the DLL/OCX: RegSvr32 failed with exit code 0xC0000409". Or rather the message is the same but the appearance of the dialog is different.

Trying again just repeats. If I [ignore] the MS VC 2017 runtime install proceeds. At about the 60% mark it appears to stall for a long time, and then starts closing applications and rebooting the computer without warning.
I've now installed real v1 on 3 Win10 machines and only this one gives this error. It's a Surface Pro v4, Win10 Enterprise 1803 build 17134.1130.
For the restart I missed the /norestart flag on calling vcredist. :/
I am a bit puzzled with the exception. Is that a dev machine by any chance?
Very good to have the restart fixed!
Nope, not a dev machine. Well, not a C++ dev machine. It does have Python, PyQt and some related things, but not QtCreator, Win SDK or anything like that. I'll dig through the installed list and see if something stands out. Anything in particular I should watch for?
Hi, i have the exact same error message on my computer. running your extension for many years now and updated to 1.0.0. Now this happens for me the first time.
Fixed it! ...but not exactly sure what was the necessary ingredient. I did:
- From "Add or remove programs" uninstalled half a dozen programs I don't use anymore
- Scanned list for anything obviously related to Qt (none)
- Ran CCleaner, used "easy clean" followed by "analyze registry" and applied all recommendations
- Rebooted
- whereupon Windows also applied an Update I didn't know was pending
- Reran v1.0.0 install
At first I thought all previews were broken for all file types, because none at all were showing. Eventually I determined I needed to 'Explorer >> View >> Options' and de-check ' Always show icons, never thumbnails'. I wouldn't have turned that on, was probably CCleaner.
For anyone wanting a targetted fix my hunch is that there's 1 or 2 registry keys that have the wrong permissions. Try searching for Dotz and/or SVG Explorer or SVG Explorer Extension.
@vmario89 let us know if any of this helps you
@maphew , thanks for investigating it.
I have added quick logging to the registration process so we can catch at which key does the process fail. The code is currently on a bug branch and the builds are available here:
https://ci.appveyor.com/project/tibold/svg-explorer-extension/builds/29933374/artifacts
To view the logs use DebugView. In the tool you can set up a filter such as Edit->Filter and type SvgSee in the Include box. Make sure the Capture->Capture Win32 option is checked in the main menu.
Once the tool is running and configured, run the installer and it will be able to catch the debug messages. Here's an example screenshot:
If you got the logs please paste them in here so we can see what's what.
On a different lead I was investigating the vcredist. It seems that the DLL registration happens before vcredist is installed and the missing runtime might cause that kind of issue. However, reading the previous comment I have doubts that this is what we're seeing here. Nonetheless the order needs fixing anyway.
I caption this error from DebugView

@DKStudio , which installer did you use?
The output looks like it is from the v1.0.0 release. If so could you please try the builds from this link:
https://ci.appveyor.com/project/tibold/svg-explorer-extension/builds/29933374/artifacts
In the builds I linked every log line is prefixed with SvgSee, which is missing in this output.
The random character output was a typo that is now also fixed.

This version (1.0.19) worked on my win 10. The 1.0.0 release doesn't work, same error message.
Thanks for the feedback!
It seems that everyone's issue got solved, so I'll close this issue.
I had the same Qt problem!
The version (1.0.19) worked for me too!
