I recently went through a lengthy process of installing GDAL and think that something may have gone awry as my IDLE is not opening. I cannot edit files in IDLE either. The only thing that works is running the IDLE.bat which then opens the Python Shell. I do have Python 2.7 installed via Arc (thus my installation for Python is in C:\Python27\ArcGIS10.4).
I've tried copying the tcl8.5 folder into the Lib folder. I've cleared the files in my .idlerc folder. Short of reinstalling Arc entirely, are there any workarounds? I can't seem to find much else that helps.As you can see in the photos, my .py files have also lost their default programs even though pythonw is set as the default program.
Can't seem to add a proper photos link, but the photos are at http://imgur.com/a/eO1Tr
