Installing .NET Framework 3.5 SP1: Receive 1603 Error Code

Answers

  • Hi Larry,

    Thank you for your post.

    For error code "1603", it's a common message that means "fatal error during installation".

    I looked into the log files that you posted and found the following error snippet:

    MSI (s) (3C:E8) [23:33:53:171]: Hello, I'm your 32bit Elevated custom action server.
    ExecXmlConfig:  Error 0x80040154: failed to load XML file: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web_mediumtrust.config
    MSI (s) (3C!D4) [23:33:53:187]: Product: Microsoft .NET Framework 3.5 SP1 -- Error 25541.Failed to open XML file C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web_mediumtrust.config, system error: -2147221164

    Error "0x80040154" means "Class not registered".
