There is no issue on my Adobe Reader at all. Plus there is more than just Adobe that will allow you to read PDF Files. All it would take is a Google Search, Bing Search or any type of search to realize that.
Plus if you knew, Adobe owned the PDF file format for the longest time. Meaning that they were the only ones who could make programs to work with it. It wasn't until recently that PDF Files became open source and anyone could develop Apps for them. It was in July of 2008. At that time Microsoft was already in the mist of their Beta Testing and released Windows 7 less than 1 year after PDF became an ISO standard. By the time PDF became part of the ISO Standard it was to late to incorporate it into the OS as they were already done with the work of additions and working on the process of fixing the bugs for final release. The PDF Standard was not needed at the time of Windows 7 release and therefor not included to have a PDF Reader. It will be in Windows 8 as the format has taken on more of a personal use format than strictly business use as it was previously.
So I really wouldnt go placing the blame on anyone. As the evidence would show that Microsoft is doing their part to incorporate a fairly new ISO standard into their OS. It is right on track to be included in the next OS being developed after the format became standard. Windows 7 was already developed, so Windows 8 would be when it would be included, which it is.
Adobe doesnt want you to get help or help you. They are pay per use software and they want their money.
So anyways, there is no issue with Adobe Reader for me. Must be a bad install for you. Uninstall and download the latest version or try an alternative. There are plenty out there.
