How i have to write custom rollback script, which has to run at the time of Rollback(installation fails).

Please provide me a detail for custom action, what should be the values we have to set for In-Script Execution Options, Execute Sequence, Condition, etc..

(Before this post we already had an e-mail conversation where I pointed narenbv at my article “Installation Phases and In-Script Execution Options for Custom Actions in Windows Installer” at http://www.installsi...00108/index.htm )

For a rollback custom action:

In-Script Execution:
msidbCustomActionTypeInScript + msidbCustomActionTypeRollback
Hexadecimal: 0x00000400 + 0x00000100
Decimal: 1280
Note: This is in the Windows Installer documentation at http://msdn2.microso...y/aa368069.aspx

InstallExecute sequence between InstallInitialize and InstallFinalize.
Note: this is mentioned in my article and also in Windows Installer documentation.

Condition: same as the custom action which you want to undo.
Note: this is mentioned in my article.
