"Error executing rsdtimetctmreadclasscheck.exe" is typically associated with RIEGL LiDAR processing software
(such as RiPROCESS or RiWORLD) and occurs when the system fails to validate time-synchronization classes within the raw data during processing.
While "full text" results for this specific error are often contained within proprietary technical logs or restricted support portals, the error generally points to one of the following issues: 1. Corrupt or Incompatible Data Files
is a background check utility. If the raw sensor data (e.g.,
files) is corrupted or was recorded with a firmware version that the 2021 software build doesn't fully support, the executable will crash.

. This error often triggers when there is a mismatch or gap in the GPS/GNSS time synchronization records required to georeference the scan data.
Re-import the trajectory data (e.g., from POSPac or RiPROCESS) to ensure the time stamps align with the scan data. 3. Permission or Pathing Issues
If the project is stored on a network drive or a path with special characters, the sub-executable may fail to launch. Move the project to a local with a short, simple path (e.g., C:\LidarData\Project1 ) and run the software as an Administrator 4. Missing Dependencies (Redistributables) The 2021 versions of RIEGL software often require specific Microsoft Visual C++ Redistributables . If these are missing or corrupted, the will fail to initialize.
Reinstall the "Redist" folder contents found within the RIEGL software installation directory.
