windows installer - VBScript will not execute correctly from MSI file -


i have vbscript wrote needs executed msi file. script correctly executes when run within windows on own, however, when run installer following error shown in log file:

microsoft vbscript runtime error: object required: 'wscript', line 3, column 2

the script below:

sub shell(cmd)     set objshell = wscript.createobject("wscript.shell")      objshell.run("""" & cmd & """")     set objshell = nothing end sub  set objfso = createobject("scripting.filesystemobject")  strcmd32 = "c:\path\pathtoexecutable.exe" strcmd64 = "c:\path\pathtoexecutable64.exe"  if (objfso.fileexists(strcmd32))     shell(strcmd32) else      shell(strcmd64) end if  set objfso = nothing

as stated before, script runs fine if run outside context of installer. setup project type vs2010 setup , deployment package (this client wishes use , cannot use else). ideas?

in "shell" sub, removed wscript first line before call "createobject()". amended line looks this:

'note absent reference wscript on call createobject() set objshell = createobject("wscript.shell")
