Hello

Thank you for posting in Microsoft Community forum.

The error log you’ve shared indicates that the w3wp.exe process, which is the worker process for IIS (Internet Information Services), was terminated due to an unhandled exception. The exception was a System.IO.IOException, which occurred when the system tried to delete a directory.

This exception can occur if the directory is being used by another process or if the directory doesn’t exist at the time of deletion. The error occurred in the CrystalDecisions.Web.CrystalImageCleaner.Finalize() method, which suggests that it might be related to the Crystal Reports software.

Here are a few potential solutions:

1. Check for file locks: Ensure that no other processes are using the directory at the time of deletion.
2. Check directory existence: Make sure the directory exists before trying to delete it.
3. Update or reinstall Crystal Reports: If Crystal Reports is causing the issue, consider updating it to the latest version or reinstalling it.
4. Check permissions: Ensure that the IIS worker process has the necessary permissions to delete the directory.

If the problem persists, you might want to consider reaching out to a professional or the support team of Crystal Reports for further assistance.
