# Troubleshooting 'libminizip.so.1 not found' errors when trying to start TeamViewer QuickSupport on NextSeq 1000/2000

**Background**

The TeamViewer QuickSupport program requires specific packages to run properly. In the NextSeq 1000/2000 series instruments running Oracle Linux 9, these packages may be missing. This results in the following error when attempting to launch the TeamViewer QuickSupport program:

"The following required libraries seem to be missing: libminizip.so.1 => not found. Please find and install the corresponding packages."

**Resolution Actions**

1. **Minimize** the NextSeq 1000/2000 Series Control Software.
2. Select the **Activities** menu in the top-left corner and open the **Terminal** application.
3. Input the command `su - ilmnadmin` and press **Enter**, then input the `ilmnadmin` password as prompted and press **Enter**.
4. Input the command dnf list installed | grep minizip and press **Enter**. If no result is output, the minizip1.2 package is missing.
5. Input the command `sudo dnf makecache` and press **Enter**.
   1. If prompted, input the `ilmnadmin` password and press **Enter**.
   2. If the command shows an error message indicating "Errors during downloading metadata for repository 'sublime-text'", then repeat command as sudo dnf makecache --disablerepo=sublime-text and press **Enter**.
6. If the command from Step #5 completes successfully, input the command sudo dnf install -y minizip1.2 and press **Enter**.
   1. If the command from Step #5 presented an error connecting to the 'sublime-text' repository, input command as sudo dnf install -y minizip1.2 --disablerepo=sublime-text and press **Enter**.
7. Once the minizip1.2 package is installed, relaunch **TeamViewer QuickSupport**.
