I have created a patch that runs successfully, however I only wish to make it install once and therefore not allow say a v1.1 to be installed twice.
My understanding is I can use install conditions to do this however I have tried some of the combinations using Install conditions such as: Installed , Not installed etc and I have not seemed to get anywhere. Sorry if this seems a silly question I just feel like I may be missing the point.
Thank you in advance 🙂
