1. Yes. Use conditions in the execute & UI sequences to determine if you should execute the action (for example, at uninstall time). 2. If you store custom action dll in the binary table using the <Binary> element, the custom action is available as long as the installer is running. 3. Custom actions can use MsiGetProperty/DTF to read installer properties. If your custom action is deferred, there is a special mechanism (and some limitations) for passing properties which is documented in the MSDN under the section about deferred custom actions. 4. Using DTF and Wix, C# will probably suit you better as long as you are certain the dot net framework is installed on the target machine.
Read the documentation on custom actions in the MSDN, the tutorial and the Wix help.

Subject: [WiX-users] Custom Actions during/post install and uninstall Am reading the tramontana tutorial - one of the best online I have to say. Just need some clarification from WIX practitioners about custom actions (in C# preferably): - Can one perform custom actions during and post installation and uninstallation ? - I guess custom action post uninstall may not make sense since the CA-implementing dll should ideally be wiped out as part of uninstall ? - Is it possible to pass value into the custom-action C# code and get some value back into WIX? Should I prefer C++ or C# - can do both, find C# more productive.
