We are using WIX 2.xx tools for a project which is kept under revision control.
I'm trying to validate that I can reproduce an exact version of our software
including the MSI distributable for historical purposes. However, I find that
if I produce an MSI file twice using the same .WXS input files the resulting
MSI is slightly different.
At first I did not think it would be an issue, a binary diff shows only about
30 bytes are different and I expected it was a time stamp or some other trivial
detail. However, if I install with the first MSI, delete the MSI, recompile
the MSI, and run the same MSI it complains that the product of a different
version is already installed and must be removed from add/remove programs.
I know I could use vomus mode to override this, but if I run the same MSI I
installed with originally it automatically asks to uninstall which is the
behaviour I'm looking for.
Is it possible to reproduce the exact same MSI twice so long as all the inputs
are unmodified?
Thanks in advance,
Jason Riffel
