Currently our installer is around 1GB in size. We want to reduce this by copying a file at install time from one location to three additional locations.
The file is 150Mb in size so potentially by not carrying it 4 times inside the installer then we could reduce the installer by 450Mb.
So in order to do this are we able to include the file inside the installer once and then near the end of the install, copy it to the other three places. Ending up with four copies of the file. And a smaller overall install file
Any suggestions welcome.
I have tried this using powershell and a custom action however the process fails the installer at the copy point.
Thanks.
