Patch works only once

Hi there,

I found a problem when using patches: a patch doesn't work again after an installation was repaired. Steps to reproduce:

1. Build a "Compressed Web-Based EXE" setup
2. Add a file to this setup (I used a pdf file with the target $DESKTOPDIR$)
3. Add the previously build setup to the patch references
4. Build a patch setup
5. Install the web setup from step 1 (I use VMWare with XP SP 2)
6. Apply the patch from step 4
-> The new file will be installed (OK)
7. Enter the maintenance mode (control panel/software...) and repair the installation
-> The new file, installed by the patch setup, will be removed (OK so far)
8. Run the patch setup again
-> PROBLEM: the new file will not be installed again!

Is there any workaround known to solve this issue?

Thank you very much,

Markus

You have to remove the patch installation from the Add/Remove Progams. It's actually a Windows Installer limitation. If you check "Show Updates" all the .msp files (patches) from your product, will appear below it as a tree. Remove the one you want and try again, it should work this time.

Thank you very much for this information. I will replace the repair functionality by removing/new installation of the application.
