[Edge] Exception when running as admin

[BlackTurtle123]

Python version: 3.7
Pyinstaller version: Git dev version
Pywebview version: latest
OS: windows 10 and windows 8 64 bit
Issue: When running the builded exe as administrator the exe fails and complains about missing RPC calls. Unbuilded version or non administrator running version don't give this issue.
Verified on 3 systems.
Why I report this issue here?
There are issues who point to toolkit/webview

Am I willing to support this:
Potentially if I can get pywebview stable working with my app I am willing to donate or look into helping solve issues. For now I am trying this as experimental to check if it runs more stable then PyFlaDesk

This error is ahem double Dutch to me. Are you getting the same error with the provided flask example if you try to freeze it on your computer?

[BlackTurtle123]

When it's freezed and we run it as administrator on my or other computers.
So freezing goes okay, running non frozen goes okay, running as non admin also goes okay.
It has some issues with rpc command it can't execute.
Exception in english:
"Exception : The remote procedure call failed. (Exception from HRESULT: 0x800706BE)
"

[r0x0r]

Can you test it with the just released 3.0.2?

I've been experiencing the same problem, and it doesn't seem like 3.0.2 has solved it for me unfortunately:

Unhandled Exception: Python.Runtime.PythonException: Exception : The remote procedure call failed.

Isolating the problem would help solve the issue.
a) Does it occur with any examples?
b) What do you do to get this exception?

Googling revealed that the problem seems to occur when running under admin
CommunityToolkit/Microsoft.Toolkit.Win32#50

EdgeHTML is buggy as af, so I would not hold my breathe that this will get fixed at any point.

[jorubyp]

a) Yes, it occurs with the Flask example
b) I run main,py in the Flask example, no window is created but the server starts and is accessible for 15 seconds, after which the error occurs.

I can live with not being able to run it as admin though (and it does work fine otherwise), I just thought I'd share that I had experienced it too.

Sorry for not providing more details originally, and again if this isn't enough to be helpful.

[BlackTurtle123]

Yes I can confirm Flask app fails I start it, it start running and after 10-15sec it fails Exact same code, exact same way of running does work as non admin Op di 20 aug. 2019 om 14:26 schreef Jo Ruby P <notifications@github.com>:

Works as non-admin, fails as admin throwing this exception here.

[josiahvehrs]

I'm getting the same exception when running as admin, when running unelevated it works just fine.

[r0x0r]

I have updated the documentation
https://pywebview.flowrl.com/guide/renderer.html#edgehtml

Closing this issue now

[amalthomas-exe]

is there a fix for this issue??

[r0x0r]

1. Use other renderer. The new Chromium is way forward
2. Do not run as admin

[amalthomas-exe]

my work requires me to have admin priviledges to write information
can you suggest any other rendered..

[r0x0r]

Use Chromium or CEF. Instructions for installing Chromium can be found here.
https://pywebview.flowrl.com/guide/renderer.html

[r0x0r]

Updated installation guide. https://pywebview.flowrl.com/guide/installation.html

[amalthomas-exe]

It's working for me ! Thanks!

[DedFishy]

You should really try to fix this issue, it's really dumb.
