Chris is correct - Autodesk licenses the ability to write a recap file to Trimble based on the end user having a license installed on the same PC for Recap Pro. If you do not have a license then this capability is prohibited. There was an issue in earlier version of TBC on the order of installation of TBC and Recap Pro - i.e. Recap had to be installed first and then TBC - which meant in some cases having to deinstall TBC, install Recap Pro and then reinstall TBC, however I believe that that has been fixed in v5.1 so that the order is n longer important.
f you have a full license of recap pro and this is still causing you an issue, please let me know so I can look into it further. Let me know if this is the cause of your issue also so I can close out this issue.
Thanks
