Help! I purchased an Acer Aspire 5735 laptop a couple of months ago pre-loaded with Vista. According to Acer's UK website the model is eligible for a "free" upgrade to Windows 7. I duly submitted an application through a third party company Acer are employing to distribute the software Mentor Media. I had to pay £12.78 for the shipping (I later discovered they ship from the Czech Republic). My application was approved as the model number and date of purchase were within their parameters. The disc arrived a few days ago but when trying to install, it asks for the model number via a drop down box. There is no sign of the Aspire 5735! I fired off an e-mail to Acer's technical support and they have told me that the 5735 is not on the list of eligible machines. Yet it is clearly shown on their website as an eligible machine. I have today rung their technical support and they have confirmed that it IS on the list but that I would have to take the matter up with the third part company Mentor Media as they have no solution, but they could not give me an e-mail address. If nothing else I want to get my money back and ask them to explain why this has been mis sold. As they are based in Czech Republic, the cost of a phone call is going to be prohibitive. Having done some digging on this Acer deal, it seems that they are a lot of issues with Mentor Media not shipping discs etc etc. Has anyone encountered this problem already or come across a solution?? I think I have been well & truly ripped off unless I can get the discs to work on my machine.
