• 1)If you have an error MSVCP71.dll and/or MSVCR71.dll was not found (or another dll file).
• 2)If GPicSync says geocoding went fine (and Google Earth file is OK) but the position wasn't written in the picture metadata
• 3)If no indications of localization appears check first your .gpx file

1)If you have an error MSVCP71.dll and/or MSVCR71.dll was not found (or another dll file).

This dll(s) should be installed by default on Windows XP. You can Google their name and download them on specialized site like "dll-files.com".

Basically, you can put them in the GPicSync installation folder or better in the system directory (on Windows XP it is C:\Windows\System32\)

It seems that MSVCP71.dll and MSVCR71.dll work together so if you have a missing message for one be sure you also have the other one.

If it's still doesn't work please contact me.

If after that you still have a problem try to install the Microsoft .Net framework.

2)If GPicSync says geocoding went fine (and Google Earth file is OK) but the position wasn't written in the picture metadata

Another software you've used may have altered or "corrupted" the picture metadata in a way that EXIFtool (library used by GPicSync) can't deal with anymore.

3) If no indications of localization appears check first your .gpx file:

A .gpx file is a "XML" file. You can open it and modify it easily in a text editor: it has plenty of tags (<tag> .... </tag>)

Gpx files have one or more <trkseg> ... </trkseg> which contain plenty of trackpoints <trkpt>...</trkpt> which says at which location you were at a precise time.

...
<trkseg>
... 
<trkpt lat="48.50517319" lon="7.13916969">
<ele>700.46</ele>
<time>2007-03-04T12:05:16Z</time>
</trkpt>
<trkpt lat="48.50517286" lon="7.13916759">
<ele>704.30</ele>
<time>2007-03-04T12:05:18Z</time>
</trkpt>
<trkpt lat="48.50517294" lon="7.13916550">
<ele>708.15</ele>
<time>2007-03-04T12:05:20Z</time>
</trkpt
 ... ... 
</trkseg>

Use "Tools"->"GPX Inspector" to quickly see the data GPicSync finds in it. If your gpx file seems fine use "Tools"->"EXIF Reader" and check if your photos contain a 'Date/Time Original' field like (Date/Time Original : 2007:04:06 14:41:02). Some image processing software erase metadata (Picassa for example keeps the metadata).
