View Full Version : Interest of update.exe

11-16-2005, 11:41 AM
Hello all,

I would like to know if Update.exe is necessary if I don't include windows installer, installscript engine and dotnet framework in my patch package

Does update.exe only run the patch with this command line msiexec /p <path to .msp file> REINSTALL=ALL REINSTALLMODE=omus ?
If so and if I can run my patch from my own executable, I won't need update.exe ?

Thanks in advance,

I believe it also does some other sanity checks, such as verifying the package it's patching exists on the machine, but running a proper msiexec command line on your msp should work fine for your no-installscript, no-new-msi scenario.
