How can I see the changes if an update for a software module is available?
Problems with reading/writing files
1) Is your file path to long? (Path length is restricted to 260 characters by Windows)
=> Solution: Try to copy file to another location / change file path
2) Check file or folder names for special characters
3) Accessing the data file with, e.g., the thaTEC:DataInspector during the measurement can cause issues due to the simultaneous file access.
=> Solution: Check your live data only via thaTEC:OS !
