[wix-users] Creating a stub to download an MSI which changes more frequently

Just download the new bundle. Like you said, it's really small. There are update options in Burn already available to make the UX seamless.

Short answers:

1. Yes.
2. Already exists but only for ExePackage and that has problems and it only continues to exist because Microsoft doesn't understand URLs.

Subject: [wix-users] Creating a stub to download an MSI which changes more frequently


I would like to build a small bundle using burn which downloads a larger main package from a URL. This already works well! But I would also like to be able to update the main package without refreshing the bundle - that is, replace the package on the web endpoint with a newer one without releasing an update to the bundle.

Today this doesn't appear to be possible because the bundle contains a hash of the package to download. To make it possible, I would have to modify the bundle code to just check the package signature and not the hash.

My questions:
1) Is there a fundamental problem with this approach?
2) If I make a pull request to introduce a 'check signature only' option, is that something that might be of use or is it not something that would be considered (perhaps because of #1)?
