[wix-users] MSI installing performance

[Roland Kieslinger]

Hello!

I captured an whole installation with sysinternals process monitor and figured something out.

The log entry "File will have security applied from OpCode." means, that the msi file gets copied to "C:\Windows\Installer", but this happens 2 times?!

First time, at the beginning of the installation: original msi gets copied to "C:\Windows\Installer\1b2b5.msi".
Second time, late at the installation: "C:\Windows\Installer\1b2b5.msi" gets copied to "C:\Windows\Installer\1b2b8.msi" (this is another copy of the same original file in the same folder like WHAT THE F***)?
At the end of the installation, the file "C:\Windows\Installer\1b2b5.msi" gets deleted.

Is there a way to completely prevent msi installer of copying the installer to "C:\Windows\Installer"?

Hello!

I'm trying to improve the installation performance of my 700 mb msi installer and I need your help. What does the following line mean:

File will have security applied from OpCode.

This line needs up to 30 seconds on specific computers. Here's some context:

MSI (s) (90:E8) [17:43:50:099]: Machine policy value 'DisableUserInstalls' is 0
