I installed Arduino IDE version 1.8.7.
It apparently installs a new version of AVRDUDE.EXE. Now it won't recognize the PICKIT2 which I use as a SPI programmer. I have re-added Pickit2 in programmers.txt and in avrdude.conf but it still does not work.
I returned to version 1.8.4 and everything is ok again. Problem with latest avrdude.exe ?
What exactly do you mean by "it still does not work"?
What I meant with "It still doesn't work": With 1.8.7. and the AVRDUDE.EXE installed along with it, and after having checked if PICKIT2 still appears correctly in programmers.txt and in avrdude.conf, it does not find my PICKIT2 programmer. It works all again after returning back to 1.8.4 with the older AVRDUDE.EXE ...
PS : I also use Atmel Studio 7 and also there it failed with the avrdude.exe coming with 1.8.7 ... That's why I suspect something is wrong with this latest avrdude.exe ...
Still not really enough information to help you. Please post the full verbose AVRDUDE output.
Ok - I reinstalled Arduino 1.8.7 and yes, avrdude.exe is overwritten. I have now version 6.3-20171130 and it was 6.3.
"PicKit2" has disappeared from the file "programmers.txt" and I have added it :
pickit2.name=PicKit2 (MightyCore)
pickit2.communication=usb
pickit2.protocol=pickit2
pickit2.program.protocol=pickit2
pickit2.program.tool=avrdude
pickit2.program.extra_params=-v -V
The output of "upload with programmer" is :
C:\Program Files (x86)\Arduino\hardware\tools\avr/bin/avrdude -CC:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf -v -patmega328p -cpickit2 -v -V -Uflash:w:C:\Users\LIEVEN~1\AppData\Local\Temp\arduino_build_358644/L7_Knob_Angle.ino.hex:i

I then installed Arduino 8.1.6 and have exactly the same problem (I get avrdude 6.3.20171130).
I then installed Arduino 8.1.5 and get avrdude.exe 6.3 with it.
Again I need to add Pickit2 to programmers.txt.
Now, doing the same upload, it all works again and I get :
