## **Installing Prizm Core on Windows**
#### **Since Prizm Core is written in Java, therefore, first of all, you need to update Java on your computer -** [**update Java**](https://www.java.com/)
1. **Download Prizm Core** for your operating system from [Github](https://github.com/prizmspace/PrizmCore)
2. Run the downloaded file (Windows - file with the extension .exe)
3. **Installing Prizm Core Windows*****:***
4. Install Prizm Core, following the instructions on the screen - Windows (as usual installing a new program).

7. In the field - **Default Account** - Enter the address of your wallet, which you will use through the node.
8. If you want to make public your Prizm node - in the **Host / IP** field, enter your IP address and click on the **Share my address** button
9. Then press the bottom right button **Save+Exit**
10. **To start Prizm Core**, we will use the **Prizm (Console) application**, you will see a command line that opens with information about the state of the node, and the Prizm Core interface will open, which we can close by clicking on the cross. Running Prizm Core will begin downloading the Blockchain database. Wait 100%
11. To view the download status of the Blockchain database, we need to open a browser and go to the address [**http://localhost: 9976/**](http://localhost/%209976/) , after entering your wallet, you will have an interface for working with the Prizm node.
12. It will take some time to download the **Blockchain database** - you can see the percentage of download progress in the lower right corner - on average, the entire database is downloaded in **12-20 hours** subject to stable Internet and sufficient free hard disk space (At least **64GB**)
13. After successfully downloading the entire Blockchain Prizm database, you can start using the network node, view detailed wallet statistics, complete transactions, start forging, and much more.
14. Forging starts automatically if your balance exceeds **1000 PZM**

## Installing PRIZM Core on **Linux**
#### **Step 1**
Now, we install **prizm-dist** and **jre**. \
\
**The Prizm core is written in Java, so we need jre under Linux:**
1. [Download jre](https://www.oracle.com/java/technologies/javase-jre8-downloads.html) ( **Linux x64 Compressed Archive** - *jre-8u281-linux-x64.tar.gz*)
2. [Download prizm-dist](http://tech.prizm.space/files/prizm-dist-1.10.4.6-linux.tgz)
3. Extract a ***prizm-dist-1.10.4.6-linux.tgz**:*
* Change to the directory «home»:\
cd /home/
* Move the .tar.gz archive binary to the current directory.
* Unpack the tarball:\
tar zxvf ***prizm-dist-1.10.4.6*****-linux.tgz**
* Delete ***prizm-dist-1.10.4.6*****-linux.tgz**
4. Extract a jre in prizm-dist folder:
5. * Move jre tar.gz to /home/prizm-dist/
* Let's now extract the zip file into that folder:
**tar zxvf** *jre-8u281-linux-x64.tar.gz*
**Delete** *jre-8u202-linux-x64.tar.gz*
**Result:**
```
/home/
|— prizm-dist/
| |— conf/
| |— jre/
| | |— [jre files]
| |— prizm_db/
| |— html/
| |— logs/
| |— run.sh
| |— run_test.sh
| |— prizmEngine.jar
```
**Step 2**
Yep!), we installed prizm-dist and jre. \
\
And so, the following step we will adjust **prizm.default.properties:**
1. We open *conf/prizm.default.properties*
2. Move to line 61 (*myAddress=)* and insert your address.
3. Move to line 250 (*prizm.adminPassword*) and insert your password.
4. Save *prizm.default.properties*
**Step 3**
**Testing and running prizmEngine:**
1. Run the *run-test.sh* and see if there are any errors?
2. I hope that number of errors is 0 and we move to next step.
3. Open the browser and input: ip:9976
**Where ip: IP = prizm.myAddress.** \
\
**if you see index.html file and stable connection then all is well.**
1. **Kill java process:**
* First command: *ps -A | grep java*
* Output of this command will give the list of java processes running on your system. Note down Process ID (PID) prizmEngine.jar.
* Second command: *kill -9 PID*
* Wait 3 minutes while databases prizmEngine are closed.
* Start run.sh and be connected to the ip:9976
* **Done!**
## **Prizm Core Interface**
If the node is configured correctly, the download of the Blockchain database will appear in the lower right corner indicating the progress in %.
{% hint style="warning" %}
### **Wait until 100% is loaded.**

## **Prizm Wallet Desktop**
{% hint style="info" %}
The **Prizm Wallet Desktop** is installed with the Prizm Core. A safe way to use a wallet.
{% endhint %}
## **Prizm Aerial**
Included with the Prizm Core is also installed a unique 3D graphics visualization software - **Prizm Aerial.**
