2. Follow the wizard
3. Update your new installation with the previous license files, “PREDICTOR.LIC” and “LIZDAT_ENDUSER.LIZ”, stored in the previous installation folder

5.04

Patch for version 5.04:
To install the patch please unzip the zip file in the Predictor 5.04 program folder. All files with the same name can be overwritten. The patch includes the following modifications:

• CRTN – Fetching Radius When using a fetching radius (calculation optimization) for CRTN models (both CRTN-L10 and CRTN-LAeq models) a problem could occur. In these cases, roads outside the fetching radius still contribute to the result instead of being ignored. This contribution was equal to the emission level of the road. This could result in extremely high levels. This patch solves this problem.
• ISO/DAL - Ground Attenuation In the calculation of the ground factors for receiver area and source area a problem could occur in ISO and DAL models. For the calculation of the ground factor in the source area, the length of the receiver area was used and visa versa. If source height and receiver height differ and if the transmission path between source and receiver has a varying ground factor, this could result in a wrong ground attenuation. This patch solves this problem.
• DAL - Barrier Attenuation In case the barrier calculation is calculated using the formulas for double screening, the attenuation for the source barrier when placing the receiver on top of the receiver barrier is overestimated. This could lead to a slight overestimation of the barrier effect of maximum 0.88 dB in a single point-source propagation or could result in a fatal error. This patch solves this problem.
• Harmonoise - Group Results In some cases, the results of groups under the main group were not correct. The results of the main group however were correct. This patch solves this problem.
