[wix-users] Burn - Progress Reporting is 50% then 100%

[Bob Arnson]

Without an additional communication mechanism, Burn only knows that the .exe is running and eventually, when it's done. Burn supports two protocols to communicate progress: the .NET Framework redists and other Burn bundles.

Subject: [wix-users] Burn - Progress Reporting is 50% then 100%

Hi,
First time post, I have a custom managed bootstrapper application (Wix 3.11) for installing a number of 3rd party pre-requisites for our application and I'm hooked into the progress events. While the CacheAcquireProgress does report incrementally (this is quick for most packages a few seconds) the ExecuteProgress seems to jump to 50% then to 100% at the end. This is not too bad for small packages that install quickly but for larger packages that take a few minutes to install the user is left with no feedback, which sort of negates the purpose of having the progress.

Example from logfile when installing SQL Server Management Studio:

Is this expected behavior? I've tried it with difference packages and searched forums with no results. Any assistance is greatly appreciated.

Thanks
