v3.11 to v4.0.0-rc.4 msi that installs certificates fails

[wmanning]

Question for the WiX team. I converted all of my MSI/burn packages from WiX 3.11 to v4.0.0-rc.4.

I have a msi where that installs certificates using the Iis extension Certificate element.
It fails to install. I had xml <InstallerPlatform>x86</InstallerPlatform> so I was thinking since it's a 64bit machine maybe I should try xml <InstallerPlatform>x64</InstallerPlatform>. No difference: same error.

Here is partial MSI log showing the error: (note the Wix4InstallCertificates_X64 in the log, this is when I changed InstallerPlatform to x64)

CustomAction Wix4InstallCertificates_X64 returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

The msi project consists of three wxs files; a bit large to post here.

Could this be a bug in Wix 4?

I can try make a simple repo if you feel it could be a bug.
I will troubleshoot further if not.

It's a bug so feel free to open an issue, but I think I have it narrowed down.
