Bitdefender is one of the best security tools to detect and disinfect any kind of viruses and malware. Installing Bitdefender online on your system is pretty simple. But when it comes to offline installations, especially for Bitdefender 2021, you might not find sufficient resources to download it and particular tutorials. Let’s find Bitdefender 2021 offline installer. How to install Bitdefender 2021 offline?
This tutorial is valid for Bitdefender Total Security offline installer, Bitdefender Internet Security offline installer and Bitdefender Antivirus offline installer.
Need of Offline Installation
Before moving forward, let’s see why anyone need an offline installation solution?
- An absence of fast internet connection: Many people have this issue. The computer in which they want to install the Bitdefender, might not have a good internet connection. The setup which typically around 450+ MB takes huge time for slow connection. In few cases, users are using mobile hotspot as an internet connection which is costly for data.
- Frequent re-installations due to PC format: Some users format their system very often, and they need do all the installation procedures again which is the waste of bandwidth.
In both of the cases, users can download the offline installer kit of Bitdefender and save it in a portable storage media such as hard drive and install it anywhere they want.
Things to know before installation:
Even if this is a complete offline installer, you will still need an internet connection for activation of the product. As we already seen that Bitdefender moved to subscription based system, it is necessary to activate the product over the internet. Don’t worry; you can do this by connecting mobile hotspot to your system for a minute and get it activated. I also recommend you to update the antivirus after installation.
How to Install Bitdefender 2021 Offline
We have already published an article about Installing Bitdefender 2016 offline in the past. This procedure is not much different than the previous one. Rather this one is simple. We will show you step by step with images.
Step 1: Download Bitdefender 2021 Offline Setup.
First, you have to download the offline setup from the official website links. Links are below. Here are the links for 32bit and 64bit. (Check How Do I Know if I’m Running 32-bit or 64-bit Windows? – It will get open in a new tab) The online installer automatically detects your type of operating system. But that is not the case for offline installation. You have to check and download the appropriate version yourself.
Download size is around 450+ mb.
What about Bitdefender Internet Security or Antivirus 2021? Don’t worry: it will automatically convert to the respective version based on your license, once you activated it.
Now, if you already have the previous version of Bitdefender Installed
Simply double click on the above-downloaded file in Step 1 (On the PC where you want to install it offline). You don’t need an internet connection to do that. The setup will ask you to remove the previous version as shown in the image below.
Choose UNINSTALL PREVIOUS VERSION and after that, it may ask you to restart the computer. After restarting again open that downloaded offline installer file and it will go ahead with installation as usual. Activate the product as the procedure is shown at the end of this article. You are done here.
Now, if you are installing Bitdefender 2021 fresh without any previous version installed: Proceed to Step 2
You have to follow the next steps to be able to install it offline without the internet.
Step 2: Download Bitdefender Agent for complete offline installation
You have to download the Bitdefender Agent. Don’t worry about the version of your key, i.e. if you have Bitdefender Internet Security 2021 key, it will automatically install that version only. You have two options. First is simple. I have uploaded the agent file for you.
File size: Less than 10 mbPlease note that above Bitdefender method is a second way to get Bitdefender Agent. You don’t need to follow it, if you have used the uploaded the Agent above.
So, after the above two steps, you will have two files. 1) Bitdefender 2021 Offline setup 2) Bitdefender 2021 Agent. You can now install Bitdefender 2021 without any internet. So if you want to install it on another PC then please take these two files with you and then copy them to your destination PC.
Step 3: Install Bitdefender 2021 Agent
Make sure you have not already installed any version of Bitdefender Program. If you have, then remove it first. Check here a tutorial about how to remove any version of Bitdefender products from your computer.
Disconnect the Internet if any (MUST). Double click on Bitdefender Agent file. (~10MB file) No need of internet in this step.
You may get a screen like Downloading package or may be a direct error window. In both the cases, you just have to close it. Downloading package window: Simply close this window. And that Error Window also.
After closing the above window or in some cases direct you will get this error window: Don’t worry this is correct.
Step 4: Install the offline setup.
Now just click on the main offline setup that you downloaded in Step 1.
You will get a screen of progress like this.
Once the installation finished for Bitdefender 2021, you will get a screen like this.
You have successfully installed Bitdefender.
Step 5: Final. Activate the Product
Now it will ask to create Bitdefender account (Simple as creating email account)
Then it will ask to enter your key. (Note that small internet connectivity is required to activate your key in this step. If your computer doesn’t have the internet at all you can temporarily connect with using your cell phone?)
Once you entered the key, your installation will get completed with your desired version (Antivirus/Internet Security or Total Security Multi Depending on you Key) you can purchase Bitdefender 2021 from here with huge discount coupon.
I choose to Sign In since I already have a Bitdefender Central account with key added in it.
Now restart your system and you are ready to use.
Well, isn’t this pretty simple? I hope that you will not face any kind of issues once you follow the above given process. Just make sure that, if you are using a laptop, the battery is fully charged because the installation might consume more battery than regular usage. If you face any kind of issues, you can uninstall Bitdefender and can repeat the above process again.
