Our fortune continues this month: We have only a few issues reported and none indicate an incoming storm of fallout from the release of WiX v7 back in April. We'll count it as skill more than luck, but either way, it's giving me time to roll the ol' icosahedrons and figure out what I'm working on in WiX v8. Gotta have something to do when staying in the air conditioning away from the bright daystar.

WixStdBA should show UAC shield when configurable bundle scope is per-machine, from @barnson, comes from me realizing that I didn’t plumb the depths of UI when creating configurable-scope bundles in WiX v7. WixStdBA correctly shows the UAC “shield” icon on buttons that trigger UAC for per-machine fixed-scope bundles. It should also do so for configurable-scope bundles when the user chooses per-machine scope. I volunteered to dig back into UI.

wix.exe crashes with ArgumentNullException in ExtensionManager.GetCacheLocations when the toolset path contains a ’#’ character, from @Tragen, reports that you get a weird error when you do something weird—specifically, when you have a
#character in a directory name. OK, maybe that’s more a question of taste than being wrong, per se, but we agree it’s legal so WiX should support it. Rob volunteered to fix this issue in WiX v8. -
Wix4CreateDatabase_X86 FAILS, Error 0x80040154 REGDB_E_CLASSNOTREG “failed to create database: BAMInvoiceDB”, from @Rajagurunathan-M007, reports a runtime failure in one of the more dependency-heavy parts of WiX: WixToolset.Sql.wixext. It’s going to take someone able and willing to set up a repro environment to dig into the failure, so this issue is now
up for grabs.
