I200: Plan begin, 1 packages, action: Install I101: Detected package: hotfix, state: Absent, cached: None I106: Calculating patch applicability for target product code:, context: Machine However, I created a WiX bundle package which include hotfix.msp, after the bundle is installed, the hotfix.msp isn't applied. When I double click the MSP file directly, the hotfix.msp can be applied properly on product A with SP1 installed. I created the hotfix.msp with 'ProductValidateFlags' equal 0x00000922. I am using WiX bundle to apply multiple MSPs.Ī MSP (hotfix.msp) is target to SP1 of product A.
