I use the full release option described in no. 5. Whenn adding files, this files will be installed. But when removing files, this obsolet files remains in the target folder.

Re: How to remove obsolete files while upgrade installation with InstallScript project?

Thanks for the answer.

I have probably formulated my question inaccurate. I have an InstallScript project. I want to create an upgrade installation for my product. By upgrade, I mean that a version jump occurs. During installation, all old files, shortcuts, etc. should be removed first. After that, the new files should be installed. How can I accomplish this task with an InstallScript project? There has to be an easy way.

Thank you in advance
