InstallAware

Hello,

I need to create updates that meet the following requirements:
- it must not be designed as web update, instead the user should do the download himself
- the update setup should only contain changed files
- the update setup must not do an uninstallation of the previous version
- the upgrade must not ask for an installation path, it should determine the path of the already installed version
- the control panels list of installed programs must show the new version number

All requirements except the last one would lead to a patch installation but these must have identical version numbers.
What would be the best way to accomplish this?

Regards

Dear Anja,

using MSI engine the only option that (partially) fits your requirements, it's to deploy a patch.
You may eventually use a custom Variable to keep track of the patch version and this may be stored in a custom key under the system registry.
Successively from your application, you may query such custom registry-key to acquire the installed version.

I do the same when I need to work with Patches, but of course, the package version listed under "Add Remove Program" will be not updated.

The above approach it's easy to implement ... but I don't know if it meets your needs as well.

Regards
