Issues while migrating Hot Fix project from WiX3.14 to WiX5

Question

Hi @robmen

Requirement to Migrate existing HotFix Setup(built on WiX3.14) to WiX5.

We are trying to compile HotFix project in WiX5 by using the attributes BaselineFile, UpdateFile in element PatchBaseline.
<PatchBaseline Id="RTM" BaselineFile="C:\Setups\65RTMMSI\BATestSetup65.msi" UpdateFile="C:\Setups\7RTMMSI\BATestSetup7.msi"/>

We started receiving the error as below

Note: Here we have input MSI file for BaselineFile attribute is build on WiX3.14 and input MSI file for UpdateFile attribute is build on WiX5.

When checked the MSI properties in Orca tool, we have observed few KeyPaths are changed and few didn't changed. Still we received for all componenets.

Could you please help us on this ?

Or Any work arounds to get these errors fixed while migrating Hot Fix from WiX3.14 to WiX5 would be greatly helpful.

Oooh, creating patches across major versions of WiX tools isn't supported. Patches are very sensitive to internal changes in the MSI, so you really want to use the same version of the tools to build your patches.
