Can anybody tell me if it is possible (and how) to replace one file in an already created .msi package with some tool without InstallShield or Wise - let's say using some command line tool:
I have a package called InstallMe.msi and inside is a file file1.exe. I have a new version of this file (file1.exe) and I want to replace the old file with this new version - just binary replacement. If I open InstallMe.msi with Orca or IS I cannot do a replacement

Thanks in advance
