Do note that there’s no universal fix as such. You will have to try out each of the below-mentioned workarounds and see which one works best in your favor. So with that in mind, let’s get started.
FIX 1: Verify Integrity of File
To begin with, you should verify the MD5 checksum of the file that you are trying to flash. During the download process, if there is a slight disruption in the network, then it could corrupt the file being downloaded. And truth be told, even a few bytes of corrupt or missing data could have disastrous consequences on your device. So you should always inculcate the habit of verifying the integrity of the downloaded file before flashing them. Here’s how it could be done:
- First off, head over to the website from where you are downloading the ZIP file. There you should find the MD5 checksum value.
- Every popular website will show you the MD5 value of the ZIP file. While the location might vary, but it will definitely be there.
- Once you have found out the MD5 value, note it down somewhere. Now go ahead and download the ZIP file.
- Once done, head over to that downloaded ZIP file folder, type in CMD in its address bar, and hit Enter. This will launch the CMD window.
- Now type in the below command in that CMD window. Make sure to replace the “filename” accordingly:
certutil -hashfile filename.zip MD5
- It will now show you the MD5 value of the ZIP file. Compare it with the one that you had earlier copied from the website.
- If they both match, then the ZIP file integrity stands maintained and all the bits of data have been correctly downloaded.
- However, if there is a mismatch in the value, then you will have to re-download the file from scratch.
- Do so and then install it. Check if it fixes “The Installer Has Encountered an Unexpected Error 2203” on your Windows PC.
FIX 2: Take Ownership of Temp Folder
The setup that you are trying to install would need access to the Temp folder in order to store the temporary and cached files. But for that to happen, your administrator account should take ownership of the Temp folder. If you haven’t done so, then refer to our guide on How to Take Ownership of Temp Folder in Windows 11. Try out the instructions listed there and it should fix “The Installer Has Encountered an Unexpected Error 2203” on your Windows PC.
FIX 3: Disable Firewall
Sometimes, the built-in Firewall might act a little bit over-protective and tends to block the app installation process, even if you have downloaded the app from a legitimate and trustworthy source. In that case, you should consider temporarily disabling the Firewall and then retry with the installation. Here’s how:
- Head over to the Start Menu, search Windows Defender Firewall, and open it.
- Then click on Turn on or off Windows Defender Firewall from the left-hand side.
- After that, select Turn off under both the Public and Private networks.
- This should rectify the underlying installation error.
