Seems they'll respond very promptly on here but not to other forums! And when they have responded, they just provide generic information, which doesn't answer the question, and then take another age to reply again. I've given up trying to get hold of them now, to ask such a simple question. P*ss poor Customer Service, Customer lost I'm afraid.Update: spoke to customer representative, issue still not resolved. Company is a scam. The product might work, but unless you sign up to the annual payments to keep software up to date, the version you buy becomes completely defunct at the first apple OSX upgrade. Parallels shouldn’t offer a one-off payment knowing this fact, it’s fraudulent. Every other piece of software I have updates accordingly, Christ I can see run software from the early 2000’s but this company monopolises on the OSX update and you either have to pay to upgrade your version or accept the version you have no longer works! Sounds like there’s quite a number of other people in this situation, shame as they could probably be more profitable if they re-thought the business plan. For me though, I’ll be removing this software as I can’t use it anyway, and avoiding Parallels for good. For any future perspective Customers, just beware of what you’re paying for and unless you’re happy to subscribe to the higher fees, it’s a waste of money!
