+## Description
+
+When exporting reports to Excel 97-2003(XLS), the error message `'This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms'` may appear. This issue occurs in environments with `FIPS` mode enabled, as the Excel 97-2003(XLS) export renderer utilizes cryptographic algorithms that are not FIPS-compliant. 
+
+## Solution
+
+To resolve the issue, render the reports into the Excel 2007(XLSX) format instead. The `XLSX` renderer does not rely on the same cryptographic routines as the `XLS` renderer and is fully compatible with **FIPS-enabled environments**. Follow these steps to enable the `XLSX` export format in your application:
+
+1. Install the required dependencies for **OpenXML** formats (DOCX, XLSX, PPTX). Refer to the [OpenXML and XPS options missing]({%slug missing-docx-xlsx-pptx-xps-export-options%}) article for instructions on enabling **OpenXML** formats.
+1. (*Optional*) Configure the report export settings to hide the **XLS** format through the [extension element]({%slug telerikreporting/using-reports-in-applications/export-and-configure/configure-the-report-engine/extensions-element%}) so that users cannot trigger an export in that format.
