You could create an "anti-patch" that installs the previous version of the file (you would however have to increment the version number of the file).

Given the question, do you think the OP has the necessary skills to do that?

Hi,
Thanks for the answer.
>>You could create an "anti-patch" that installs the previous version of the file (you would however have to increment the version number of the file).
I cannot create an "anti-patch" because 2 error was done:
1. The msp patch was created as non-uninstallable.
2. The InstallShield project which was used fro this patch creating was lost.
The msp patch is very simple. It replaces some files only.
I found the solution:
I found in the registry ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products") the product and then set the "Uninstallable" value to the "1" (instead of the "0") for this patch.
Thank you for you help

Congratulations. You now know how to make your target machines unstable by allowing uninstallable patches to be uninstalled.
Do you understand why a patch would be made uninstallable? Do you know what a patch is?
