Problem capturing UAC windows with MashCentralAssistant

[kevimax]

Hello everyone !

Translated by Google from French :D

To begin, thank you for this immense and excellent work.

I installed Meshcentral out of curiosity, now I don't plan on not working with it!!

This is not really an issue, but rather a feature request.

I have browsed github, reddit, it seems to me that my request would be appreciated.

When using the MeshCentral Assistant, there may be problems with administrator access and capturing UAC windows.
I recompiled meshassistant by modifying manifest.app with:

That solves the first problem because it requires the user to accept the elevation to start assistance. However, capturing UAC windows still doesn't work and that's a real problem in my situation. you must always ask the user to click "yes", even to install a simple print driver...

Previously I was using a lightweight agent from anydesk, it did this just fine without installation.

Is it possible to add an option to change this behavior ?

Thanks a lot !

Hi Kevimax,

Can you elaborate a bit how you recompiled the manifest.app to make MeshCentral Assistant always open with administrator access?

I have same issue here as lots of my clients are not very computer literate and it's hard to ask them to right click on the MeshCentral Assistant and run as Administrator.

However, if they right click on the MeshCentral Assistant to run as Administrator, I don't need to ask the user to click "yes" again.

Hi Jim-Young

To do this, you must fork your own GITHUB repository, then modify the manifest.app at the line :

requestedExecutionLevel level="administrator" uiAccess="false"

and compile again.

Personally I used the "action" feature of GITHUB to compile :)

Thanks kevimax,

I can only find "manifest.json" in public folder, I don't see manifest.app for some reason.

[kevimax]

sorry, it's app.manifest

Thank you kevimax.

I've forked and changed the line to
requestedExecutionLevel level="requireAdministrator" uiAccess="false"

But when I went to Action, I don't have any workflow and I can't find Visual Studio 2015 as Ylianst said he used that.

Sorry I'm not a developer and not quite sure how to use github. Basically I want to try changing those settings in source code and test it.

I'm not sure why Ylianst doesn't set to run as administrator as default like anydesk. When I work with my clients, very often I need administrator permission to do something in Device Manager or other uninstall&install, but it's hard to ask the clients to do something they don't understand.

I would also have greatly appreciated an operation like anydesk..

To compile with action, you must add a folder "/.github/workflows/" in the repository of your fork with inside a file named "dotnet-desktop.yml" which contains:

I tried the dotnet-desktop.yml workflow, apparently, it ended up with error where 47 line is nothing there. Then I tried to remove that empty line, the error message says 46 line

Now, I start different approach that whenever I need administrator permission I just download an agent to client's computer and when you connect the agent it pops up UAC, then user only needs to say YES once.
