FAQS 1 : MSI Packaging & Re-packaging.

Custom Actions

1. How to add custom actions to run only during patching

Add "PATCH" To condition in custom action

2. Name few best practices for creating a Custom Actions

* Do not use custom actions in your package that require elevated privileges to run.

MISC

1. Which runs first "Run" key or Active Setup

Applications launched by Active Setup will run first. Activesetup is using to configure the userprofile settings if no entry points exists in the package and this will be running only once for a specific user.

2. If you extract a COM information through registering the dll or OCX file which tables will it be reflected

3 Can you elaborate the driver handling via device driver?

4 Apart from APP search what tables you use to find whether the particular application is installed via MSI tables?

5. What is the meaning of Launch condition Office2007

Only proceed the installation if value of "Office2007" property is less then "office2003" property

6. What are the attributes you set for files going under c:\Winnt\System?

2. During typical execution how many of them are used.

Only 2 tables are used during any typical execution

MSI Sequence

1. Can we control Uninstall GUI

MSI >=4.5

1. What is Per User Application (PUA)

An application capable of being installed, updated, run and removed by a standard user without elevation is called a PUA

2. What is the minimum OS on which MSI 5.0 will get installed

Windows 2008 and Windows 7

3. What is single package authoring / dual purpose package

A dual purpose package is a windows installer 5.0 package that has been authored to be capable of installing an application in either the per-user or per-machine installation context.

4. What is the limitation of PUA/DPP

FreeBasic : Code : runas in FreeBasic

FAQ's MSI Packaging & Repackaging

There are two version of the document. I have tried my best to have correct information and if you find any issue or wrong information then please inform me about it. The download location for them are as follows

• Release Version: http://sourceforge.net/projects/mayadeploy/files/FAQ/. Just download the latest version
• Working Version: http://mayadeploy.svn.sourceforge.net/viewvc/mayadeploy/trunk/FAQ/FAQ on MSI packaging and repackaging.odt. This version is a work in progress and can have wrong information.
