With Qt, you can reach all your target platforms – desktop & embedded – with one technology and one codebase, minimizing your time-to-market and maintenance burden. Qt is available under a dual-licensing model — you choose what’s right for your needs. This application failed to start because it could not find or load the Qt platform plugin 'windows'. Available platform plugins are: minimal, offscreen, windows. Reinstalling the application may fix this problem. ----- OK ----- I tried to put qwindows.dll from Qt installation, but it still doesn't work.

Reason Solution This error may occur if any of the Qt assemblies (or) inner folders missing in the QtBinaries. Make sure the all the Qt assemblies are present in the QtBinaries folder, check the list of assemblies with QtBinaries folder from WebKit HTML converter installed location. This error may occur when using the assemblies and QtBinaries from different version of WebKit installer. M ake sure the Syncfusion assemblies and QtBinaries are using from the same version of WebKit i nstaller.

The latest version of WebKit installer can be downloaded from the below link, The specific version of WebKit installer can be downloaded from the below link, After installing WebKit HTML converter the assemblies and QtBinaries will be available in the WebKit installed location. Emma marrone cd schiena downloads. Example: $System Drive: Program Files (x86) Syncfusion WebKitHTMLConverter XX.X.X.XX This error may occur when the WebKitPath (i.e., p ath of QtBinaries folder) has non ascii characters.

So, m ake sure the QtBinaries full path does not have any non ascii characters.

If you start the bash terminal supplied by the NEURON 7.5 installation, and unset PYTHONHOME and then run nrnpyenv,sh it will print a number of environment variables needed for python to work when launching nrniv. In fact nrnpyenv.sh is automatically run when you start the bash terminal and exports the PYTHONPATH (needed to import neuron if you launch python) and PYTHONHOME and NRN_PYLIB ( needed if you launch nrniv -python). In your case, I suspect you need a more extensive PYTHONPATH when launching nrniv in order to find QT.

One way of diagnosing is to compare the result of import sys sys.path when launching python and nrniv -python which may indicate what is missing. Another hint can perhaps be gleaned by launching python and importing a module and then determining its location with.__file__.

Thank you, the unset and run of nrnpyenv.sh produced sensible output, but all looks like it should and that I already have when I run nrniv_python. I am still nervous about forward vs double vs backward slashes though. Can inherent complication of mixing windows vs unix systems.

Having re-installed Neuron, of course I can't run any of my scripts (I presume because the paths are all wrong), but I wondered if I should await advice before re-setting that up in case it is the very way I did it that created the problem in the first place?
