Software Deployment

Who cares?

Honestly, if it really bothers you, just install via both methods to 2 different VMs and compare them! Or
- take a 'Before' snapshot
- install via MSI/MSP
- rename the 'Uninstall' key (so that WI assumes it's not installed)
- install the via EXE
- take an 'After' snapshot
- spend many subsequent hours wondering why you bothered

I really have to wonder at what appears to be a total lack of diagnostic skills. It really isn't hard to work this stuff out.

Hi VBscab,

I was just trying to find out "why" was that happening. Also I found that when I uninstall and reinstall the same application, the size is getting increased .

It is because of the method of guessing used by add/remove Programs to retrieve these additional data, and puts this wrong information.

Anyways, thanks for your comments. :)

ARP doesn't guess anything. It receives its data from the costing actions in the MSI. My suspicion would be that the EXE is passing some parameter to MSIExec (if it uses it) or setting some property/feature level/whatever and then calling WI APIs which might result in a slightly different install. As before, a delta snapshot will nail that. Alternatively, you could log both installs and compare the logs.
