First we need to find the installed package. For that enable Windows Installer logging.

1) In run open gpedit.msc or you can google how to open group policy editor

2) Expand in left panel Computer Configuration -->Administrative Templates --> Windows Components --> Windows Installer

3) On right panel open Logging and Enable it and in option Logging voicewarmupx

4) Restart your PC

Now Windows Installer logging is enabled. Next we need to find and uninstall the conflicting package.

1) Open windows %temp% (can be opened by typing %temp% in run) and delete all files. If something cant be deleted leave it.

2) Run the .NET Framework 4 installer again. After the installer fails, close it.

3) Open windows %temp% again and open the log file (file would be MSIxxxxx.LOG, eg:MSI232f1.LOG)

4) Search for a line saying PROPERTY CHANGE: Adding NEWERVERSIONDETECTED property. Its value is {xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx}'. Value will be different depending on the package that is already installed.

5) Open command prompt and run msiexec /uninstall {xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx}

6) Now try installing .NET Framework 4 Installer again. This time it will succeed.

Also don't forget to disable Windows Installer logging. Using the same way you enabled it.
