I downloaded the tool from the link you provided, copied the .exe from the "Release" folder to my C:\Program Files\ArcGIS\Mobile10.0\bin folder as the Instructions suggest. Everytime I try to run the tool I get a "No License available" message?? I have ArcGIS Mobile 10 installed and am currently running a local single use license of ArcEditor 10.
The application starts after I get the no license message and click OK to dismiss it; it seems to let me open a .db file, I select the layer and it chugs away (lots of features), it lets me select export modified features and then generates an error (attached).
Am I supposed to get the "no license available" message....and is that the problem? I can still open the cache in ArcGIS Mobile and view the modified features so I don't think its corrupt, it just won't let me Post.
