I want to launch IDA debugger for one 64-bit exe file and it fails, have tried with more samples, but result always the same. Here is that I do.Launch IDA Pro (64-bit)Select Debugger -> Run -> Local Windows Debugger from top menu.Select my file.  and click OK.At this point getting such prompt.  and click Yes.Finally got such error: And after that this-one: It happens all the time, have tried it on a few different VMs on my actual machine. I'm using full version of IDA v6.7.141229.I believe something has to be configured, as the last error says something about wrong parameters, can someone advice?
IDA cannot launch debugger for 64-bit exe files
ida;x64
Since IDA is a 32 bit process, it can only debug x64 binaries remotely (source). To do that, you need to use the IDA X.X/dbgsrv/win64_remotex64.exe file and start a debugger. Once the debugger is running, you can connect to it remotely and debug. You can check this tutorial for more specific details.
