On Windows Server 2003 with IIS 6.0 when trying to run a perl CGI (cartit.cgi) which has

use Crypt::SSLeay;

I get the error: “Can’t load ‘C:/Perl/site/lib/auto/Crypt/SSLeay/SSLeay.dll’ for module Crypt::SSLeay: load_file: access is denied” in the web browser after first installing Crypt-SSLeay.
I had already installed a precompiled Crypt-SSLeay package for Windows from: http://theoryx5.uwinnipeg.ca/ppmpackages/

Testing the script from a command prompt gave expected results with no error messages but it refused to run from IIS.

It seemed as if this was a permissions issue, however, based on my solution- it may be the source was linked to some dependency of OpenSSL as it was a requisite for the machine which compiled the Crypt-SSLeay Perl module I am using.

This one had me going around for a bit. Here is what I found. You must install the binary OpenSSL for Windows before installing Crypt-SSLeay otherwise the results will not be what you expect. So if you installed Crypt-SSLeay without FIRST installing the OpenSSL
binary version, you will need to remove the package in PPM. You should then install OpenSSL from a source listed here: http://www.openssl.org/related/binaries.html and finally reinstall Crypt::SSLeay from command prompt as below:

C:\ppm install http://theoryx5.uwinnipeg.ca/ppms/Crypt-SSLeay.ppd

I uninstalled the PPM, installed the OpenSSL binary version, and finally reinstalled Crypt-SSLeay again. Now at the command prompt when I run the script I get a dialog box stating:
“MSVCR71.dll was not found. Reinstalling the application may fix the problem.”

At which point I went to dll-files.com and downloaded the msvcr71.dll file and placed it in a folder that is in the path (Thanks dll-files.com!). Now the script works from the IIS web server as well as the command prompt.
