Hi All, I am running into an interesting problem that hopefully someone here
can shed some light on. I generated an MSP successfully and I was able to
verify through Orca that all files will be patched as expected. However, when I
apply the patch to an actual installation, the files are not being replaced!!
Here's an overview on how my MSIs are authored. I thought it is easier to give
you an idea this way than explaining it in words.
RTM CU1(non-Wix) CU2 (Wix)
-------- ------------------ -------------
C1/F1 C1/F1' C1/F1'
C2/F1 C2/F1' C2/F1'
C3/F1(key) C3/F1'
C3/F2 C3/F2'
C is a component, F is a file and the character ' is an update to the
corresponding file's earlier version. Also, notice that the component C3 was
added to CU1 with multiple files in it (does not follow WIX best practice but
WIX was not even considered for patching at that time).
So, when I authored patch WXS file using WIX, I made sure to include all the
C1, C2 and C3 components in a PatchFamily using the ComponentRef element. Once
the MSP is generated using RTM as baseline, I am able to apply the patch
successfully on RTM build. However, when I try it on a CU1 installation, the
install finishes without any errors but does not replace file C3/F2 although it
replaces C3/F1 - which is the key.
1. Isn't WIX supposed to patch files in a component if the key file is
modified?
2. Is there a way to supersede a non-Wix generated QFE like CU1 through
WIX generated patch like CU2?
Thanks,
