Slip-Streaming Patches

Slip-Streaming is a process which applies MSP to the MSI where MSI has not been installed on the system. If the Service Pack is in MSP format, then it can be directly installed on the system where the application is present.

How is Slip-Streaming done?

In this phenomenon, MSP is automatically added to the MSI file itself and one can directly install the changed MSI.

It can be called used by the following commad:

msiexec /p abc.msp /a abc.msi

Disadvantages of Slip-Streaming Patches

  1. The patch alone can never be un-installed.
    If the patch has some problems, we will need to uninstall the entire application and to install the base application again without any patch. This is a very tedious process.
  2. The user will not be aware of the patch application on the core MSI.
  3. Consecutive patches can't be applied.

There are better methods to handle patches with Windows Installer. However, when this doesn't work, Slip-Streaming can be a Just in time solution... :)

Thanks to sunil and harsha who shared this information with me.

Slipstreaming

Vijay,

It is not mentioned, but slipstreaming sjould be avoided as much as possible.
It is not the best practice to get updates on a software package. it is a last solution if nothing else works.

Thats True...

Erik,

Very true. Slip Streaming should be avoided to a maximum extent. Thats why I had mentioned at the end of tip that,

"There are better methods to handle patches with
Windows Installer. However, when this doesn't work, Slip-Streaming can be a Just in time solution..."

One should take care to deploy pathes through installer, rather than slip streaming. As you say, only if Installer fails, this can be employed.
