<div dir="ltr">Guys, I've tried everything suggested here in multiple variations, even to the point of rebuilding from the source code following the instructions in the FAQ, and I'm still getting the same output as is shown in my previous reply to this thread. I'm not sure what the difference is between what I'm doing and what Andre (one of the previous replies) is doing to be able to get the correct results. Would anyone be willing to give me a detailed step-by-step, starting with downloading "<a href="http://download.osgeo.org/proj/proj446_win32_bin.zip">http://download.osgeo.org/proj/proj446_win32_bin.zip</a>" and unzipping in a windows environment (I placed everything in C:\proj). See Andre's post above for the inputs and outputs. The second set of output coordinates is exactly what I need to get, but my output is just zeros and asterisks. Thanks so much folks for your help... I feel like I'm just missing something simple...!</div>

<div dir="ltr">Thank you, I tried what you said, and what I'm getting as output is as follows when I run the same batch file:
<div><br>
</div>
<div>
<div>WGS84-NAD27</div>
<div>* * 0.000</div>
<div>WGS84-NAD27PAft</div>
<div>* * 0.000</div>
<div>NAD27-NAD27PAft</div>

<div>I'm thinking my EPSG definitions might be messed up somehow... but I also tried copying from
<a href="http://spatialreference.org" target="_blank"></a><a href="http://spatialreference.org" target="_blank">spatialreference.org</a>, and still I get the same output. (It seems like the 4326 EPSG is not working... ) Any further ideas? Your second result is the correct and expected conversion
result... not sure why I'm getting asterisks and zeros for the same command! :/ Thanks again for your help!!</div>
