How can I create installer in single file that contains 3GB application

[marbel]

The size of my application is about 3GB. I need to share it with my clients in a single exe file, because they will have problems downloading several files into one directory.

When my application size was below 2GB, everything was fine. Now I get an error:

"Disk spanning must be enabled in order to create an installation larger than 2100000000 bytes in size." 

When I set DiskSliceSize=3073741824
I get another error:

"Value of [Setup] section directive "DiskSliceSize" is invalid."

I think I found the answer :(

"No, this is not supported. Disk spanning is the only option."

I also found the answer from 2006 and it is really funny :)

(What, "easier to *download* from the Internet?  True enough, but you'll be 
on Medicare before that download finishes).

Has anyone used SMART INSTALL MAKER?
