Cannot finish the install: ImageAreaSelect plugin is missing or it is not installed properly

Hia again :)
Thank you very mucho for replying to me, I´ve forgot to mention that I´ve read that issue, and taked care of the names of the files. Thanks!
Anyway, After re-reading over and over again the readme, I´ve noted that my version of imgareaselect was 0.9.1 instead of the old 0.4.2. The newer one has folders, wich weren´t in the older.
So, I´ve installed the older to follow the instructions carefully, and I´ve installed the module, but with this errors:

    * warning: fopen(sites/default/files\private\.htaccess) [function.fopen]: failed to open stream: No such file or directory in C:\xampplite\htdocs\soporte\sites\all\modules\pdfstamper\pdfstamper.module on line 189.
    * warning: fwrite(): supplied argument is not a valid stream resource in C:\xampplite\htdocs\soporte\sites\all\modules\pdfstamper\pdfstamper.module on line 197.
    * warning: chmod() [function.chmod]: No such file or directory in C:\xampplite\htdocs\soporte\sites\all\modules\pdfstamper\pdfstamper.module on line 198.

I must add that I´ve created the symlink file manually, simply cloning the jquery.imgareaselect-0.4.2.min.js inside the imgareaselect-0.4.2 folder (inside of pdfstamper/js folder) to a new file called jquery.imgareaselect inside pdfstamper/js folder.

I´ve double checked the installations of the other modules (specially the ImageMagick installation, wich is working).

Probably because of that error, when I tried to create a pdf stamp document this appears:

* ImageMagick command: start "window title" /D"C:\xampplite\htdocs\soporte" /B "C:\Archivos de programa\ImageMagick-6.5.4-Q16\convert.exe" "sites/default/files/pdf_de_prueba_para_membrete.pdf" -border "2x2" -bordercolor "black" -quality "75" "sites/default/files\private\pdf_previews\pdf_previews_5.jpeg"
* ImageMagick output:
* PDF File Membrete de Pirulo has been created.

ImageMagick reported an error: convert.exe: `%s': %s "gswin32c.exe" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGridFitTT=0 "-sDEVICE=pnmraw" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72" "-sOutputFile=C:/DOCUME~1/Victoria/CONFIG~1/Temp/magick-bNv1zlNX" "-fC:/DOCUME~1/Victoria/CONFIG~1/Temp/magick-jJa0ZQt1" "-fC:/DOCUME~1/Victoria/CONFIG~1/Temp/magick-Zk91GiTJ" @ utility.c/SystemCommand/1881. convert.exe: Postscript delegate failed `sites/default/files/pdf_de_prueba_para_membrete.pdf': No such file or directory @ pdf.c/ReadPDFImage/611. convert.exe: missing an image filename `sites/default/files\private\pdf_previews\pdf_previews_5.jpeg' @ convert.c/ConvertImageCommand/2800. 

Again, thank you for your help and guidance!!!

Hi again!
I´ll check that again, but I think it has the permissions.
I´ve installed it on Windows XP SP3.
Thanks!

Hi again!
I´ve installed on a test hosting this module, and couldn´t use Magick module (have to use GD2 because they said Image Magick is old and outdated, and bláh bláh), and this is the output that I´ve got (I´ve checked the chmod and just in case tested with 777, with all possible permissions:

# warning: fopen(sites/default/files/private/.htaccess) [function.fopen]: failed to open stream: No such file or directory in /home/public_html/sites/all/modules/pdfstamper/pdfstamper.module on line 189.
# warning: fwrite(): supplied argument is not a valid stream resource in /home/public_html/sites/all/modules/pdfstamper/pdfstamper.module on line 197.
# warning: chmod() [function.chmod]: No such file or directory in /home/public_html/sites/all/modules/pdfstamper/pdfstamper.module on line 198.

So far, I´ve noted that:
= The folder sites/default/files\private\pdf_previews is not created by the module, so I´ve created it manually widh chmod 666.
= The .htaccess module is not created by the module either, so I´ve created it and added it inside that /pdf_previews folder (and tried it inside the /private folder aswell), with this code inside:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /system/files/private
RewriteBase $path
RewriteRule ^(.*)$ $1 [L,R=301]
</IfModule>

And I still get the error.

:S September 2009?
I´m so sorry! I´ve never read you email! But I know that it cannot have gone inside spam folder. So this is weird...
I know that I didn´t solve this problem at that time. I´ll try to install it again and check out if the problem remains (I´ve got a new installation of Drupal that requires this module).

I´m very sorry for not answering you and I sincerely do apologise, yash!
