This issue is caused by antivirus scanner on your machine. Can you please check antivirus scanner logs and see if there is an exception logged for c:\config.msi? Also let us know which antivirus you have on the machine? We (Microsoft) would like to reach out to them to change their product to work better with installers.

Log file indicates some other application (like Antivirus scanner) is opening the backup file without FILE_SHARE_DELETE after MSI creates/moves it.

MSI (s) (D8:C8) [11:31:49:844]: Product: Microsoft .NET Framework 4.5 -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2329. The arguments are: 32, C:\Config.Msi\b8265.rbf,

Workaround: disable antivirus and install .Net 4.5 on the machine then enable antivirus again.

Open cmd Type in the command “net stop WuAuServ” (disable windows update) Go to Run (you can do this by pressing Win + R) and type in “%windir%” (this command let you go to your windows system folder) Find the folder “SoftwareDistribution” and rename it as “SDold” Then, go back your previous command prompt and run the command “net start WuAuServ” Now, try to install .NET Framework again
