# How to troubleshoot Decode File Client error "The feature you are trying to use is on a network resource that is unavailable."
Users may experience authentication issues that prevent successful access to the application when the Decode File Client software is installed on a shared computer and used by multiple users. The article outlines the symptoms of the problem, explains the underlying cause, and provides step-by-step instructions to help restore access and ensure the software functions correctly for all users.
####
#### **Error Message**
"The feature you are trying to use is on a network resource that is unavailable (Figures 1 and 2).
Click OK to try again, or enter an alternate path to a folder containing the installation package 'DecodeFileClientSetup\_3.0.4.0.msi' in the box below."
**Figure 1.** Decode File Client error message "The feature you are trying to use is on a network resource that is unavailable."
**Figure 2.** Follow up error when clicking OK: "The path 'C:\Users... cannot be found."
A user may encounter this error when attempting to launch software installed on a shared PC. When clicking on the Desktop shortcut, the software will launch appropriately for the admin account or original user that installed the software, but throws the error for other users logged in to the same computer.
Error message typically appears when an admin/user installs the software in a file location that is not accessible to other users. The shortcut points to a location that is not the default location where the software is usually installed.
The target location of the shortcut should point to the default location. Right click the Shortcut icon on the Desktop and select Properties. The target file address of the shortcut should point to \**C:\Program Files\Illumina\Illumina Decode File Client\**
#### **How to resolve the error**
**Option 1:**
Uninstall the existing software in the admin account and re-install in the user account. The software installer is available from the [Decode File Client Product Files](https://support.illumina.com/array/array_software/decode_file_client/downloads.html) page. The installer should save the Decode File Client files in the default location: \**C:\Program Files\Illumina\**
**Option 2:**
1. Delete the existing shortcut.
2. Navigate to **C:\Program Files\Illumina\Illumina Decode File Client** and right click on the **DmapFileWebServiceClient.exe**. Create a shortcut and place it somewhere more accessible, eg, the Desktop.
If there are no files in the folder, locate the installation files (including .exe file) and copy to the default folder: **C:\Program Files\Illumina\Illumina Decode File Client**
The **DmapFileWebServiceClient.exe** file should be in this folder so all users have access to it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

GET https://knowledge.illumina.com/microarray/decode-file-client-software/microarray-decode-file-client-software-troubleshooting-list/000010027.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
