# Moving ENERCALC SEL to a Different Computer

How to move ENERCALC SEL and its data files to a different computer.

## How can I move my ENERCALC SEL to a different computer?

Follow these simple steps:

1. Internet Deactivate ENERCALC SEL on your current computer.
2. Uninstall ENERCALC SEL from your current computer.
3. Locate ENERCALC data files that you want to move to the new installation and back them up to a portable memory device. These could include:

* *Project Files*: File extension is “EC6”. Default location is C:\Users\\\[username]`\Documents\ENERCALC Data Files.`
* *Custom section data files*: If you have any custom section data files, they are typically stored in `C:\Users\Public\Documents\ENERCALC Common Data Files`, and they will have the extension "TPS" and will include *USR* in the file name, such as EC6\_STL\_USR\_W\.TPS.
* *User defined load combinations*: If you have any user defined load combinations, you will want to copy and move the file named LoadComb.tps, which is typically saved in C:\Users\\\[username]`\Documents\ENERCALC Data Files\.`

1. Locate your Product Control Code. IMPORTANT!!!: Use the most recent one that was sent to you, as this establishes the Allowed Version that you will have access to, and the features and functions that will be available.
2. Download the installer: <https://install.enercalc.com/ECSEL20_SETUP.EXE>
3. Run the installer on your new computer (pasting in the latest PCC in the process).
4. Launch the installed software and use “Internet Activate”.

## 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://docs.enercalc.com/sel-faq/setup-and-licensing/installation-activation-lice/making-changes/moving-my-software-to-a-differ.md?ask=<question>&goal=<endgoal>
```

`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.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
