I KEEP GETTING AN “EXPECTED STRING EXPRESSION” ERROR. WHAT DO I DO?

After you’ve been prompted to enter text into iolite (such as during licence activation) you might see a dialogue telling you that Igor expected a string expression, with a window that looks something like this:

StringErrorDialogue

This is just an issue where if you enter some text into an Igor prompt, it needs the text to be surrounded by double quotation marks. Just make sure that the text you enter into the prompt has an ” at the start and end of your text, and you should be good to go!
