IDF editor is not opening and its icon remains in the taskbar
Hi I am trying to open IDF editor but it does not open. The icon is shown on the taskbar but the editor is not opening.
Plus whenever I click an IDF file I receive an extension error saying the file's extension is invalid (even on E+ example files)
Not EP-launch
@Wolfgang Kaiser what version(s) of EnergyPlus are you using IDF Editor for? Each EnergyPlus version should have a distinct executable file for IDF Editor.
Have you looked at this answer or this one or maybe this to a similar question
