InstallAware

I made an installer. It is "Compressed Single Self-Installing EXE", where it has to install and copy some files onto target system. Afterwards I made patch (upgrade installer) where it creates new website on IIS server using "Create IIS Site" function.

My questions are:

1) During the patch installer, it prompts for the original source media, the solution for that is to run the self extracting .EXE file again that comprises the compressed build, and then I have to browse through the folders to the original media source. I wonder if there is another solution for original source media?

2) The result of patch (upgrade installer) is that the new IIS Site has been created on IIS Server, but the question now is how can the installer delete the created WebSite on un-installation (i.e. how can I tell uninstall .EXE file to use "Delete IIS Site" function and provide it with the specific site index on un-installation)?

3) If the entire destination folder on the target system is moved manually from place to place, how can the patch (upgrade installer) recognize the new destination path?

Finally, looking forward to your respond,

Thanks in advance

1) Please see the help files for patch source resolution - this question is thoroughly discussed there.
2) I'm afraid if your original installer does not create/delete the site, with the patch, there is no way to delete the site.
3) This is not possible - when you move installed files around, you are technically breaking the installed state of the product.
