Dear Advanced Installer Support Team,
One of our customers are found out that some important files are missing after a product upgrade, which is a serious problem for us. I also managed to reproduce the problem.
Reproduction steps:
1. Install version 24.1.0 of our product on a random PC. After the installation you can see the following 2 files on the hard drive:
C:\Program Files\Therefore\SX-PDF-Lib\pdf-xpansion-windesktop-x64-T4.dll
C:\Program Files (x86)\Therefore\SX-PDF-Lib\pdf-xpansion-windesktop-x86-T4.dll
At this point both files have a version number of 14.3.4.0.
2. Apply a hotfix, aka copy over a newer version (14.3.9.0) of those 2 files.
3. Install version 24.2.0 of our product which contains the same version (14.3.4.0) of those 2 toolkits files. We did not touch that toolkit in our setup, the files remain untouched. After the installation the 2 toolkit dlls are gone from the relevant folders.
Expected behaviour would be leaving the newest (patched) version (14.3.9.0) in those folders.
Please see the screenshots I'm attaching and let me know if you have any questions. Please handle this incident as kind of urgent, without those dlls our product is barely usable.
Best regards,
Zsolt
