Light setup problem

[rtomsmith]

I am developing the capability to carry out patch updates via a light (NOEXE) setup.

I am building my patches with NOEXE set. (My setups are compressed Web-based EXEs.) I have modified the updates.mia script to do an Extract 7Zip on the patch EXE and to Run Light the extracted setup.exe program. The patch updater seems to execute just fine until it gets to the Apply Patch command. Windows Installer reports "Invalid command line argument" on return from the Apply Patch.

My new code in the updates script passes "/s REBOOTCOMPUTER=FALSE REBOOTNOW=CANCEL" to the extracted light patch update program which is the same command line I pass to a full version (which works fine). So what command line paramaters do you think WI might be complaining about? Exactly how does IA construct the command line that gets passed to WI and how might this be failing?

Thanks for your help.

Light mode setups are not designed for use with patches. I can add this as a wish list entry from you for implementation in future versions.

Ouch - wish I had known that before investing the development effort.

So there is no way to get patches to be nice and small I guess? The size of my full setup EXE is about 1.7MB. I was hoping to get a typical patch down to about 500K. NOEXE builds get there just fine, but a full patch EXE for only a few bytes of changed data is around 1.2MB.

How about serving a full non-patch light mode setup instead? How big is that one instead?

Yes, that one is about 800K which is better. However that means an uninstall/install type process which I was hoping to avoid since it's much lengthier than a patch.
