getting ImageMagick to work with vB (on Windows)

[Psalmist]

Yes, I did set the path. That was not the problem (although, if you have spaces in your path, that could be a problem on Windows (if vB doesn't know to put quotes around it), so just to be safe, I installed ImageMagick to C:\ImageMagick\ instead of the default C:\Program Files\ImageMagick\).

The problem is described in a bulletin from Microsoft. Apparently it's a somewhat common problem with CGI (or FastCGI). (By the way you have to use CGI or FastCGI on Windows because the ISAPI module version of PHP is not stable on Windows, because it's not really thread-safe as Windows applications need to be.)

The problem is that when you're running in CGI/FastCGI, the internet user guest account (IUSR_*your_machine_name*) is denied access to the Windows system program Cmd.exe (which I guess vB needs in order to execute ImageMagick). So you have to explicitly grant read and execute permissions on Cmd.exe to the IUSR_*your_machine_name* account.

Here's the bulletin from Microsoft:

(In case anyone else running vB on Windows runs into the same problem.)

Thanks
