To utilize the Crystal Reports Merge Modules with InnoScript and Inno Setup, first download the zip file, which contains the CR Merge Modules in an installable MSI format. InnoScript will automatically incorporate the file name into the script. It is essential to eliminate any remaining CR files from your script that InnoScript has not already removed. You can identify these file names by consulting the Reference and Components list provided by InnoScript in the generated script. This list should be used alongside the InnoScript Debug log to ensure that all necessary files are identified for removal. Additionally, the ORCA Editor can be employed to examine the contents of the MSI file to determine which files should be discarded. You may include these files in the unsafe file list utilized by InnoScript, ensuring their automatic removal.
