Merge multiple .sid files together

Question

Hello,

I am trying to merge together multiple aerial photos together to run a classification and they are currently .sdi files. I tried running a Mosiac to New Raster but I get the below error when geoprocessing finishes. Is there anything else I can do to process Mosiac?

Right. I could not find the decode utility without downloading the Extensis SDK as possibly having to compile it so I went back the previous company in the off chance that the OP was not comfortable in that environment.

I just saw this about MrSID Lidar: https://pro.arcgis.com/en/pro-app/latest/get-started/release-notes.htm#

Functionality removed at ArcGIS Pro 3.4

The following subsection notes functionality that was removed at ArcGIS Pro 3.4.

MrSID Lidar

MrSID generation 4 (MrSID Lidar MG4) format is no longer supported. Use the Convert LAS tool to convert .las, .zlas, and .laz files between different LAS compression methods, file versions, and point record formats.
