I have a few Installers (Basic MSI Project). All of them have MSSQL as a prerequisite. All of them are set Release->compressed. 

As a result I have a few big setup.exe files (one for each installer). It is ok but MSSQL prerequisite is compiled into each setup.

I would like to have this prerequisite outside of compressed setup.exe files and common for all of them.

I thought that I can do like below:

• I've set for Release -> Setup.exe (tab) -> InstllShield Prerequisities Location: Copy From Source Media.

Then I have a separate folded on the disk "" and there is MSSQL Prerequisite. It is ok.

But the Setup.exe is still the same size. Why?

How to keep MSSQL Prerequisite only outside of setup.exe.

I've tried many configurations. Always setup.exe or directly *.cab file has the same size as before changes.
