# Troubleshooting SAV errors on the NovaSeq 6000

There are two types of errors relating to Sequence Analysis Viewer (SAV) on NovaSeq 6000:

**SAV is not able to install due to permissions errors**

* This is likely due to an incorrect path.
* To troubleshoot, make sure that SAV is being installed under the C:\Illumina directory.

**SAV is not displaying run metrics properly**

* For instruments on NovaSeq Control Software (NVCS) v1.1 and earlier, make sure that SAV v2.1.8 is being used.
* If the instrument is on NovaSeq Control Software (NVCS) v1.2 and later, make sure that SAV v2.3.4 is being used.

If the issue persists, contact Illumina Technical Support (<techsupport@illumina.com>) to determine the next steps.
