There can be multiple reasons for this, and this post will help you fix some of the know reasons.

Fix Windows Installer Error Code 2755
Before we start, make sure to launch the installer with admin permission before using these methods.
- Redownload the installation setup package
- Add the SYSTEM user in the installer
- Add an Installer folder in the Windows directory
- Check if the setup file is encrypted
You will need to use an admin account to execute these steps.
1] Redownload the installation setup package
The issue can occur if the downloaded package is damaged. Redownload the installation setup package to a different location, and run it and see if that works.
2] Add the SYSTEM user in the installer
SYSTEM user is a built-in user for Windows used by the operating system and by services that run under Windows. By default, the SYSTEM account is granted Full Control permissions to all files, ensuring it can do almost anything.
If the installer is throwing this error, you can add the System user to the installer and run it under its permission, ensuring the error doesn’t occur anymore.
- Right-click on the installer, and select properties
- Switch to the Security tab, and then click on the Edit button to open the Permissions window
- Next, click on Add button, and then on the Advanced button > Find Now
- Select the System user from the result, and add it to the list\
Done that, rerun the installer, and the error should not occur again.
3] Add an Installer folder in the Windows directory
Whenever a software installer runs, Windows unpacks the files into the Installer folder located at C:\Windows. If the folder is missing, then installation will fail. So navigate to the folder and check if the folder is available. If not, then right-click and create the folder with the same name. Now run the installer and check if it works.
4] Check if the setup file is encrypted
The last thing you can do is check if the installer is compressed or encrypted. It can be easily identified by looking at the properties of the file.
- Right-click on the installer, and select properties
- Switch to the General Tab and click on the Advanced button
- In the Advanced Attributes window, uncheck these two options
- Compress contents to save disk space
- Encrypt contents to secure data
- Apply the changes, and then launch the installer to check
