Bug work-a-round

While looking at how to make Windows 7 search inside PDF's I found that I am effected by a PDF iFilter bug. With this link as the fix namely download and install the "Adobe PDF iFilter 9 for 64-bit platforms"

Apparently this plugin can be used on other Microsoft products such as sharepoint, exchange and sql to get full text indexing going for PDF.

Here is a screenshot of the problem as it appears on my Windows 7 Pro 64 bit install.
