Installation problem with RMagick-1.14.1_IM-6.3.0-7-Q8

Hello everybody,

I tried to install RMagick-1.14.1_IM-6.3.0-7-Q8 in my windowsxp system.

C:>ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]

C:>gem -v
0.9.2

C:>rails -v
Rails 1.2.3

For that I download the RMagick 1.14.1 binary gem for Ruby 1.8.5 from
http://rubyforge.org.

After downloading I got the following files :

ImageMagick-6.3.0-7-Q8-windows-dll.exe
rmagick-1.14.1-win32.gem
RMagick-1.14.1.tar.bz2
README-RMAGICK.txt
README-RMAGICK.html
README.html
md5sum.txt

But can’t get software.md5 file inside the .zip…

After that I used ImageMagick-6.3.0-7-Q8-windows-dll.exe as per
instruction>
But at the end I got an error like unable to execute file : ppm
ShellExecuteEx failed; code 2.
The system cannot find the file specified.

Whats this error .
