What to check
Reinstallation is useful when evidence points to a damaged client installation. It is less useful when the same failure affects every workstation. Establish the scope first, then prepare a recovery path for the affected machine.
Troubleshooting steps
- Record the SAP build, component architecture, connection settings, and required extensions. Save local custom files and close SAP sessions.
- Have an administrator remove and reinstall the client using approved media matching the server environment and SAP's installation instructions.
- Apply required prerequisites, restart when instructed, and test the client before restoring optional components.
Confirm the result
Verify login, a representative document, and report preview. Use approved elevation for installation; routine SAP use should not depend on disabling endpoint protection or UAC.
