Linguistically, a compound is a word made up of several words. In common usage, a compound is an expression made up of several words but written with no internal spaces.
Using the second definition, if you write "currently-installed" with a hyphen rather than a space between the words "currently" and "installed", then it's a compound. There is the related question of whether there is a good reason for using the hyphen, and a good reason might be the resolution of a potential ambiguity by grouping together the words of a constituent with the hyphen. This is one of the rules given in the Wikipedia article on English compound -- look under the heading The following compound modifiers are not normally hyphenated. And, by the way, the list given there includes expressions like "currently installed" among those not normally hyphenated.
For the linguist's idea of what a compound is, we'd need some evidence that "currently installed" is a word. I can't imagine what that would be -- it doesn't seem at all like a word, to me. For one thing, it doesn't have the peculiar strong initial stress that many noun compounds have.
