Error while trying to run project: Unable to start program. The request is not supported

Question

I'm having problems launching an application with VS2017 on Windows 10. Starting in Debug mode, a popup apperars with the message:

Error while trying to run project: Unable to start program ''. The request is not supported.

If I launch without debug, it runs. If I run it and then attach to the process, it attaches. If I run with administrative privileges, then it debugs (but I can't develop with administrative privileges). I'm owner of the folder where is source code and where project is built.

It works like a charm on previous PC with Windows 7.

Any idea?

Answer 1

You need to check "Use Managed Compatibility Mode" in Tools|Options|Debugging|General.

Answer 2

In the end, i found the solution. The problem is ConEmu set in "Aggressive mode" and as default terminal: it capture my application execution and do some unknown interference. I removed that setting, and my app work like a charm.
