Difference of Small upgrade and minor upgrade

Small and minor updates are very similar. The only difference is that in a minor update the
product version is increased (in any of the first thee fields), while a small update leaves the
version number unchanged or increases only the fourth field of the number. You can update
your product with a small or minor update package only if the product code is unchanged.
To replace an existing application with a package that has a different product code, a major
upgrade is required.

MsiLockPermissionsEx table

MsiLockPermissionsEx Table in Windows 7 enhances the functionality over LockPermissions Table.

Q&A: Windows Installer Basics:Part 2

General Questions

1.when repackaging a legacy scripted installation (setup.exe) through setup capture,why should you exclude the HKLM\software\microsoft\windows\currentversion\uninstall registry key if it is captured?

Every windows installer installation automatically creates its own values in this hive to support uninstallation

 2.How do you set permissions on a folder without editing the LockPermissions table directly?

            1.Write a custom action that executes to modify permission through the ACLs or Secedit.

          2.Use permission tab for the create folder object (wise studio) or

            Use properties of the folder (Installshield)

3.Which Custom action in MSI script (wise package studio)  can use for nested installation.

            Install MSI from Installation

4.Suppose Windows Installer installs package.msi ;package.msi has created a registry value, this registry value has been over writen by some other application later.Will the registry key that is a keypath to a component be  repaired when self healing is triggerd through the short cut?

Why we get “Internal Error 2705. Directory” error during an MSI installation?

This error is due to as there is an error in Directory table of the MSI.

Generally occures while a directory entry that references something non existent as its parent. If you ignore the ICE 03 validation error (Similar to the below mentioned Eg.) while developing the MSI,During the installation you will be getting the “Internal Error 2705. Directory” error.

Eg: of an ICE 03 error :

Orca validation reports an ICE03 error: “Not a valid foreign key; Table:Directory, Column: Directory_Parent, Key ):newfolder1”

 This can be fixed by editing the Directory table.The wrong entries in the ‘Directory table’ will be highlighted in red colour.
