What can explain the variancy of msi size respect to InstallShield version ?
I noticed that building the same project with InstallShiel 2023 and InstallShield 2014 the size is significantly differents. I extract the msi and I saw that some dll (for instance, binary.ISSetup.dll) have different size (bigger in 2023). Can you explain me the reason why ?
Thanks,
Loic
ISSetup.dll contains the Installscript run-time engine.
Its likely that the differences in size that you are seeing in this file is due to changes in the Installshield codebase - for example bug fixes, or enhancements when each new version of Installshield is released.
There are close to 10 years worth of changes between 2014 and 2023.
I ran a quick a test and can see that in IS 2023 R2 it was 1.55MB, whilst it actually decreased slightly in size for 2024R2 to 1.51Mb
What sort of overall size increase are seeing between your installers?
