## Contacting us

If you cannot find an answer or solution in the Analyst user guides/, contact our support team at [support@solargis.com](mailto:support@solargis.com).

To help us resolve your request efficiently, include the following information in your message:

- A description of the issue, question, or suggestion.
- A screenshot (attached or pasted into the message body), if applicable.
- The **SDAT log file**, if you are reporting an error or bug — this can significantly speed up the investigation.
- Your data file(s), if the issue is related to data — for example, a Solargis Analyst exchange file, a `.db` file, or any other relevant file. Provide large files via a shared link.
- Information about the machine where you are running Solargis Analyst: platform, OS version, RAM size, and screen resolution.
- Your Solargis Analyst software version.

#### Attaching the SDAT log file

Solargis Analyst writes its internal log to a local text file. Attach this file when reporting errors or bugs, ideally immediately after the error occurs.

To locate and attach the log file:

1. Copy the path `%LOCALAPPDATA%\SDAT` and paste it directly into Windows Explorer. The folder contents will be displayed. The full path is typically `C:\Users\<User>\AppData\Local\SDAT`. You can bookmark this folder for future reference.
2. Locate the file named `sdat_runtime.log` and attach it to your message.

> **Tip:** You can also paste `%LOCALAPPDATA%\SDAT\sdat_runtime.log` directly into your email client's attachment dialog to locate and attach the file without navigating to it manually.
