I purchased and Unlimited AVS4YOU license years ago...why...because I don't use this program very often. A couple of times along the way I upgraded computers and the license would update. Not so this time around. When I dug into it, I can see the new license agreement does not allow switching computers...Sweet. If AVS4YOU is going to have this policy...fine...it is your business...run it the way you want... At least have the decency to explain clearly what you mean by and Unlimited License in your marketing/sales literature. You could also have the decency to "grandfather" those systems you sold under the original unlimited agreement. It would not be that difficult.
As an engineer who travels, I once purchased an unlimited car rental upgrade plan...several years later they changed the agreement rendering my unlimited car rental upgrade plan useless. Fine...here's how I handled that one...it's been over 20 years since I have rented a car from that company and will walk or Uber before I ever rent a car from them again...I can assure AVS4YOU will never see another piece of my business again and I suggest if you choose to do business with this company, understand they market with "forked-tongue". Unlimited means only for your current computer...something goes wrong with your computer, you need to repurchase a license for your replaced motherboard or computer...they strategically do not explain this on the page where you have the choice between an Annual License or Unlimited License. Stay away from this company's product...it may function fine, but do understand what you are paying for.
