[WiX-users] MSP uninstall issue related to update shared files

[Chunlin L. <cl...@es...>]

Hi,

I has two product MSI setups, A.msi and B.msi. They have some shared files installed to "Program Files\Common Files". I need update some of them in our Service Pack. I created A_sp1.msp and B_sp1.msp to update those shared files.

I have A and B installed on one machine. I also applied A_sp1.msp and B_sp1.msp to the machine. The shared files updated correctly. But when I uninstall either A_sp1.msp or B_sp1.msp, those shared files rolled back to previous version. My questions is: Is there a way to make those updated shared files not roll back to previous version if any of A_sp1.msp or B_sp1.msp is not uninstalled?


Thanks,
Chunlin
