Daniel,<br><br>Yes, the same mapfile worked under MS4W on a 32-bit machine. I have verified that this same problem occurs using the x86 binaries from Tamas' site run in the current x64 environment. The source image is in PNG format in order to make transparency work well on the client. (My client is Silverlight-based, and PNG is the only supported format that supports transparency). The source image does have a world (*.WLD) file which contains these values (file is generated by running gdal_translate on a geotiff image):<br>

Thanks to all who've been helping me along. I'm getting close to having x64 working now. I've worked through a slew of issues over the weekend, most related to permissions. My latest issue is that mapserv.exe, when invoked via IIS 7's FastCGI (classic mode) module, is returning blank images. GetCapabilities is working fine, and the GetMap images are the<br>
right size and format, but they're blank. Here's my setup: I downloaded and installed the x64 binaries (from Tamas, thanks!) into a single directory (C :\mapserver\).<br>

Why do you think the problems are related to IIS7/x64? Have you verified that the same mapfile produces valid maps under MS4W or another server environment?<div class="im"><br>

Your DATA statement points to a PNG file. PNGs do not carry any georeferencing information by default, and the EXTENT line is not a replacement for missing image referencing info. Did you create a world file (.wld) for your PNG to specify the geographical extents of the image? That could very well explain the blank map.<br>
