Quick Patch problem
It seems that I misunderstood something regarding Quick Patch for an installation.
I had an original installation for some of my clients, lets call it version 1.0.0
Then I created a series of Quick Patches, v126.96.36.199, v188.8.131.52, v184.108.40.206
Everything was Ok till now...
As I have some new clients without v1.0 installed, I decided to create a new install, version 220.127.116.11 which will include all the Quick Patches in the initial install. So I did it, and now when I try to Quick Patch the initial installation, the v1.0.0 I get an error saying:
The upgrade patch cannot be installed ... because the program to be upgraded may be missing or the upgrade patch may update a different version of the program...
I have verified, the Product code installed (HKEY_CLASSES_ROOT\Installer\Product\ is the same as in the Update.exe.
In the InstallShield.log at the end I get error 1642.
What did I do wrong? What is the correct procedure for such case ie how can I incorporate the QuickPatch in the installation so that the new QP will work with both installations (quick patched or newly installed)?
And what should I do now to correct the problem?
Thanks in advance for any help.
