I just purchased the calsync and downloaded the zip file. I haven't clicked on it yet because even though I spend HOURS reading before purchasing, this doesn't seem straightforward at all to me now. The email I received after purchasing has 3 files. Are they the same as the zip? I purchased this for some ease in my life. Is there a step by step process that I can follow?
