# AppEnhancer - Export/print failure with multi-page TIFFs when using PDF format
## n some AppEnhancer environments, exporting or printing a document that contains a multi-page TIFF fails when Use PDF Format is selected. This behavior was reproduced in AE 22.2 and AE 24.4, so it was not isolated to one version
- Multi-page TIFF → **Export as PDF** = fails [AppEnhancer 22.2 p9 - Issue with Export/PrintAppEnhancer 22.2 p9 - Issue with Export/Print](https://app.hubspot.com/go-to/6409159/0-5/45665490178)

- A temporary workaround was to export only a page range that excluded at least one page from the multi-page TIFF; exporting the full TIFF caused failure [AppEnhancer 22.2 p9 - Issue with Export/PrintAppEnhancer 22.2 p9 - Issue with Export/Print](https://app.hubspot.com/go-to/6409159/0-5/45665490178)
**Cause**
The final resolution showed this was not just a missing patch issue. **Patch 11 for AE 22.2** was required, but the customer’s **Rendering Service account configuration** was also preventing the fix from taking effect. When the service was configured with the **username@domain** format, export/print continued to fail. Changing the Rendering Service to **Local System** or using the traditional **domain\\username** format resolved the issue .
**Resolution**
1. Apply the required AppEnhancer patch for the affected version.
- AE 22.2 → **Patch 11**
2. Review the **Rendering Service** logon configuration.
3. If the service is using **username@domain**, change it to either:
- **Local System**, or
- **domain\\username**
4. Restart the Rendering Service and retest export/print using a full multi-page TIFF
**Notes for Support**
- The issue may look like a patch failure even when the correct patch is installed.
- If the customer reports Patch 11 did not help, verify the Rendering Service account format before escalating further 1.
- This ticket was closed after the customer confirmed exports were working once the service configuration was corrected 2.
