Yes, you can execute redistributables as part of your update.

After a bit of RTFM my original question is reasonably nonsensical. I was researching Wix etc installer builder so nothing much made sense to me last night. Building your original installer is explained at Step 5 @ http://wyday.com/wybuild/help/walkthrough.php - DIY.

What I actually meant to to ask is "Updating Version in Add/Remove Programs with MSI Installers" at https://wyday.com/forum/t/817/updating-version-in-addremove-programs-with-msi-installers/#post-8202

My concern is with MSI uninstallation and repairs. It's probably something I need to test

== original nonsense left for posterity and just so I don't later delete something that actually did make sense in hindsight. Also, it might (or not) be useful for anyone trying to get up to speed Wix ===

I'm looking to wyBuild & update. My app is based on the Autodesk RealDwg package which needs to include anything up to 60 MSM merge modules (ugh, I know). Is this in wyBuild's territory or is it more of an MSI-specialty Advanced Installer thing?

I'm hoping it's not an esoteric MSI thing because Advanced Installer is oneI've found so far that does MSI with MSM merge modules plus patch-updates and that version is US$1,499. & $499/yr maintenance OUCH. That sucks because the $399 & $139/yr would be fine if it made patches. It does auto updates but doesn't build them.

[edit] I tried Advanced installer and it built a broken MSI as soon as I added an MSM to it. It also completely obfuscates anything Wix-related. That's a shame because it's actually usable by mortals. Installshield was more confusing than Wix, a bigger installation than Windows and more expensive than your looming election (good luck with that). The others .. meh.

The downside of hiding all the Wix is that it hides all the Wix so you never know what is _really_ going on. I can Automate some of the XML building with the Visual Studio add-on called "Wax" ... and learn more Wix ... it still seems to be the most painless (in the long term) way to do MSI installers, for differing values of "painless"

[edit] Just so you don't think anyone had less fun than you last weekend, after trying Advanced Installer, Add in Express, Install Aware, MSI Factory, Install Shield (in case I win a lottery) and I forget whatever else, I'm back to Wix angle brackets, "Wax" (Visual Studio Add-on) and also Wix# at http://www.codeproject.com/Articles/31407/Wix-WixSharp-managed-interface-for-WiX which is basically a C# transpiler into Wix but it does actually use Wix XML. A lot of the other (expensive) tools don't use Wix XML and it makes them really hard to debug which is especially troublesome for Wix. IsWix would be good if it still worked, which parts of it it don't.

None of the ones I like do patching in any sensible manner. So, here we are. Patching for MSIs that don't upset the Add/Remove programs or is whyBuild a-ok with MSM modules that throw lots of ICE-validation warnings because Autodesk I'll just stop there. ??

wyBuild 2.6.x doesn't build installers. The next version will. The current version only makes update patches.

Yes, you can install MSI's and MSP's from wyUpdate, the only caveate is that you need to disable "advertised shortcuts". See: http://wyday.com/wybuild/help/walkthrough.php (step 5b)
