Is there any way to set install depedency for two msp patches, as patch 2 will only be installed if patch 1 is installed.

If patch 2 requires patch 1 you could handle this with version numbers: patch 1 would increment the version (i.e. Minor Update) and patch 2 would target only that version.

Hello, Stefan.

Could you please tell me will your advice work in case of administrative package?

You see I need to generate an msi-package which must include distributive and number of patches.

And I need to be sure that there will be now installation of patches which require other patches, not included in the package.

Thanks in advance.

I think it should also work with administrative images, but it's not recommended. See MSI documentation topic "Windows Installer Best Practices", section "Avoid patching administrative installations", and topic "Patch Packages":
QUOTE
Users can install applications and updates from a network administrative image. Although patch packages can be applied to administrative installations, the recommended method to deliver updates is to have users install the original application and then apply the patches to the local instance of the application on to their computer. This keep users in synchronization with the administrative image. If a patch is applied to the administrative installation, all clients of that administrative installation must recache and reinstall the application to receive the update. Until a user recaches and reinstalls, the user is unable to install-on-demand and repair installations from the patched administrative installation.
