If those programs use EXE or MSI databases you can usually do a silent (unattended) install.

For an EXE, this varies, but NSIS installers run silently if you pass the /S switch on the command line.

To install an MSI database, you can use this macro:

!macro InstallMSI FILE TEXT

  Exch $0

  Push $1

  Push $OUTDIR

  GetTempFileName $1

  StrCpy $1 $1 -4

  SetOutPath $TEMP

  File "/oname=$1.msi" "${FILE}"

  Banner::show /NOUNLOAD `${TEXT}`

    ExecWait '"$SYSDIR\msiexec.exe" /qn /i "$1.msi"'

  Banner::destroy

  Delete "$1.msi"

  Pop $OUTDIR

  Pop $1

  Exch $0

!macroend

And to invoke it:

Section

  !insertmacro InstallMSI "C:\Path\To\MSI\File\On\Dev\Machine.msi" "Text displayed while installing"

SectionEnd

In this case, the compiler would compress "C:\Path\To\MSI\File\On\Dev\Machine.msi" into the NSIS installer and the MSI file will be extracted at runtime and installed. Note that this function installs the MSI database without showing any UI. To show a full UI, change the "/qn" to "/qf" in the ExecWait line.

You can set class paths with WriteRegStr.
