How to determine whether a computer is running a 32-bit version or 64-bit version of the Windows operating system
A simple way to check your system: Start --> Computer (right click) --> Properties
Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Please make sure All Users is checked
Just keep the defaults as in the picture checkmarked
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.
Please copy and paste log back here.
The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.
