MINOR upgrade problem

[Zsolt Kollarits]

Dear Advanced Installer,

We tested your MINOR upgrades - when we are leaving the product code untouched - some years ago: back then it was not working, some files were simply not replaced, even if the new .exe came with newer versions of the affected files.

Now after upgrading to AI version 22.8, we performed some more tests, we hoped the issues with MINOR updates are fixed already. Unfortunately we got the same result: some files are still not replaced.

Test scenario:
1. We have a lot of files DLLs) with e.g. version number 1.0.0.0
2. We build an exe with version 1.0.0.0 and install it on a PC
3. We upgrade our DLLs and ALL of them have version 1.1.0.0
4. We build a 2nd exe with version 1.1.0.0 using the files in step 3
5. We install exe 1.1.0.0 over 1.0.0.0
Result: in our case 4 files were simply not replaced and they still had version 1.0.0.0. Most of the files have 1.1.0.0 version after the upgrade.

Note: those 4 files were probably used by Windows Explorer, as we got a "Windows Explorer needs to be closed" message during the installation, also the tray, and Windows Explorer was closed temporarily for 10-20 seconds. So we got the idea, that maybe a system reboot will fix those 4 files, but they still had 1.0.0.0 wrong version even after the reboot.

Are you aware of such problems of your MINOR upgrade mechanism?
Do you have any suggestions how we could create MINOR releases? We would like to start deploying smaller exe packages, with faster installation time, however those packages should be stable and should replace all of the files.

Best regards,
Zsolt

Hello,

I´ve just sent your a logfile via email.

For example TheNavigator.exe and TheViewer.exe files were not upgraded by the MINOR upgrade. We can confirm that before the installation both of them existed in the install dir with version 33.1.1.0, then we installed package 33.2.0.0 which really contains both of the files with version 33.2.0.0, but still after the installation we see 33.1.1.0 versoins.

Best regards,
Zsolt

Hello Zsolt,

Now after upgrading to AI version 22.8, we performed some more tests, we hoped the issues with MINOR updates are fixed already. Unfortunately we got the same result: some files are still not replaced.

Please note that this is not a bug, but rather a limitation of that feature.

Some files are not replaced by our setup

Please see the reply from my colleague Eusebiu to your post a few years ago, as that explains why this is happening.

Best regards,
Catalin
