Problem description

I'm using Cmder. Since today (Windows update?), I'm having lots of errors attempting to create a new ConEmu instances. Example error (always same error):

ConEmuHk64, PID=3860

cmd.exe: PID=3860
Injecting hooks into PID=7280
FAILED, code=-703:0x00000005

Steps to reproduce

1. Open ConEmu (either via Cmder or directly executing ConEmu64.exe, using cmder's init.bat script)
2. 
   
   
   3.

Try run Cmder.exe as administrator

I'm experiencing the same thing with the {git bash} in GitExtensions. Same error starting from command line, 'C:\Program Files (x86)\GitExtensions\ConEmu\ConEmu.exe -basic -run {git bash}'.

Works ok if run either as administrator. I do not have this issue on Win7.

ConEmu version: 190310
Windows 10

I have confirmed the same issue exists in version: 190623

Having same issue when trying to create a Task for VS2019.
Used this as reference: https://conemu.github.io/en/Tasks.html#create-new-task

This is my Task:

Text:
cmd /k ""C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvars64.bat"" -new_console:t:"VS2019 x64"

Result:

Any hints how to solve this?

I think that for my problem is all about the company's security policies. Running as admin resolves the issue, but then I access the files as administration and it's not what I really want. I think I won't be able to use ConEmu on the office workstation.

Ok, it seems running ConEmu as administrator bypasses this error.
Thanks @elegos ! 😄

[elegos]

It would be interesting to know more about that error in order to address it and, in case, ask the security administrator about an exception, or why it is required to inject hooks to let ConEmu work correctly and try to figure out a workaround for the "trimmed by security" computers.

I have this issue (also on a corporate laptop so I'm guessing this is caused by one of the Windows 10 mitigation policies which group policy turns on). What's interesting is that apart from the MsgBox, it doesn't seem to cause any issues. I'm guessing the hook dll is used for features of ConEmu that I don't use so I'm wondering if I could just fix this by forking ConEmu and removing hook injection.. or adding an option to remove it..

Lots of system applications do perform hook injection on corporate laptops but they invariably do it via driver based injection via APC or IDT patching. Generally speaking, this isn't the kind of thing you'd expect apps to be doing, so I'm not sure this is a good design choice for ConEmu because Microsoft are increasingly hostile to user mode hooking and ConEmu is always going to be one Windows 10 update from being broken...

EDIT: Ah, looks like that already exists: "-cur_console:i". This fixes all my issues.

Another solution, as referenced in
https://conemu.github.io/en/ConEmuHk.html
is to disable inject ConEmuHk.dll entirely, but see link above for potential issues.

Doing this on my corporate laptop solved the problem which would cause me to dismiss this dialog numerous times during software builds.

This works for me.
