# Install the Sibe add-in for SolidWorks

You can have the Sibe add-in running in SOLIDWORKS® 3D CAD with one setting to think about, and two housekeeping steps that stop most install problems before they start.

## Before you start

* Windows, with SolidWorks installed and **closed**
* Administrative privileges on the machine: the installer raises a Windows User Account Control prompt

## Clear the decks first

Most failed installs are leftovers from an earlier one.

1. Open `C:\Users\your_username\AppData\Local\Temp`. If you cannot see it, turn on **View → Show → Hidden items** in File Explorer.
2. Press **Ctrl+A**, then **Shift+Delete**. Skip anything Windows says is in use.
3. Restart the machine.

## Install the add-in

1. Sign in to your Sibe workspace and click **Add-in** in the left sidebar.
2. Click **Download the SolidWorks add-in**.
3. Open the downloaded file and click **Yes** at the Windows User Account Control prompt.
4. Click **Next**.
5. Read and accept the license agreement, then **Next**.
6. Keep the default install location, or change it if you need to.
7. Click **Install**, then **Close**.
8. Restart once more so SolidWorks picks the add-in up.

Or grab it straight from here: [Download the Sibe add-in for SolidWorks](https://app.sibe.io/static/add-ins/solidworks/latest.exe).

**Rolling it out across a team?** Ask support about the silent install. It takes the click-through out of the process.

## Check it worked

Open SolidWorks and look under **Tools → Add-Ins**. Sibe appears in the list. Select it under **Active Add-ins** *and* under **Start Up**, so it loads every time.

Then open the Sibe panel in the right-hand task pane and set it up: sign in, pick your workspace, choose your local cache folder. The next article, **Complete the Setup Guide**, picks up from there.

**Two rules for the local cache folder**

* Keep the path short and near the root of C:, for example `C:\SibeCache`. Windows caps a full file path at 260 characters and files past that will not open.
* Never put it inside OneDrive, Google Drive or Dropbox. Two things syncing the same files fight each other.

## Troubleshooting

**Sibe isn't in Tools → Add-Ins.**
Restart the machine and look again. If it is still missing, run the installation through a second time.

**It's listed but doesn't load.**
Both boxes need selecting: **Active Add-ins** and **Start Up**.

**The installer won't run.**
Approve the User Account Control prompt when it appears. If your IT team locks that down, send them this article and the [security overview](https://help.sibe.io/en-us/article/sibe-installation-from-a-security-perspective-lqsdi6/).

**Antivirus blocks the download or the install.**
Whitelist the installer and the domains below.

**Domains to whitelist**, all HTTPS on port 443:

* sibe.io
* app.sibe.io
* api.app.sibe.io

## Common questions

**Where do I download the add-in?**
Sign in to your Sibe workspace, click **Add-in** in the left sidebar, and click **Download the SolidWorks add-in**. There is no separate download page.

**Why clear the temp folder first?**
It clears out partial files from earlier installs so the installer starts clean.

**Can I change where it installs?**
Yes. The install location is the only setting in the installer. The default works for most people.

**Do I have to restart afterward?**
Yes. Restart once more after the install.

**Can I install it on several machines at once?**
Yes. Ask support for the silent install.
