Testing your vbs before putting it in the msi will not ensure it will work, due to what gvlaarho mentioned, that wscript functions are not supported. However, in most cases (i.e. if you are doing wscript.createobject) you can just drop the wscript. If you are doing wscript.quit or wscript.sleep etc though you'll have to find another way as it can't be done - in the installshield forum there are some rather lengthy posts on how to work around these issues if you really need to. Its a bit annoying that you have to modify your scripts for msis though.

For example, here is a way to do a sleep as a sub that I copied and pasted from some helpful soul:

Sleep(5)

Sub Sleep(ByVal iSleepPeriod)
' Note: Timer returns the number of seconds that have elapsed since midnight.

Dim iStartTime, iEndTime, iCurrentTime
On Error Resume Next

iStartTime = Timer
iEndTime = iStartTime + iSleepPeriod

Do While Timer <= iEndTime
Loop
End Sub

God bless google :)

Hope this helps

1720 means beat your head against the wall repeatedly.

Wise published an article to assist with resolving the issue but ultimately I think VBScript is kinda pointless with MSIs until VBScript is properly supported.

Hi there,

I would recomend to test your VBScript before inserting it into the CustomAction.
Just create the text file with *.vbs extension and put all your VBScript code there.
it will simulate the Custom Action.
In most cases it works

Best wishes,

Just a remember :

In custom action this : wscript.createobject isn't accepted but only CreateObject is well accepted.

Also the same for all the wscript.XXXX (For example wscript.quit; wscript.sleep ...)

Good Luck

Hey, thanks Gvlaarho! Maybe that will ease some of my pain. I've found VBScript painful to use with MSIs because of the good ol 1720 error. Hopefully it's just the way I code that is causing some of the grief.

KKaminsk, your about as confident about your programming capabilities as I am.
