Here's something new that might help:
I have tried downloading and installing the Adobe iFilter 9 for 64-bit systems
. Afterwards, Windows search still does not work.
However, the installation instructions include this:
"After installing the PDF iFilter, it is recommended that you set your system PATH environment variable to the "bin" folder of the "Ifilter" installation. For example, from the "Control Panel\System\Advanced\Environment Variables" tab, append to PATH "C:\Program Files\Adobe\Adobe PDF iFilter 9 for 64-bit platforms\bin\" and then restart the computer. "
I Windows Search for "environment variables" (an example of its utility) and find the control panel. However, it is not totally clear to me that these instructions are for Windows 7 and I don't want to screw up my computer.
There are two sets of variables, for User and for System. The system variables are not edit-able. The current path points to Windows Live. Should I change that path?
