Detecting VBScript Runtime Engine

[Tim_Mayert]

I have the following VBScript to hide the Uninstall cancel button on uninstall:

Const msiMessageTypeCommonData = &H0B000000

Set rec = Installer.CreateRecord(2)

rec.IntegerData(1) = 2
rec.IntegerData(2) = 0

Message msiMessageTypeCommonData, rec

This works good, but on one machine that I know of it will fail with a VBscript runtime error.

I don't know if it is the code itself or if the machine maybe does not have the VBScript runtime engine.

If it is the engine then is there anyway I can determine if the runtime engine exists and if not then set my custom action with a condition not to launch if the runtime engine is not found.

Now if it is the code then can anyone point out where the mistake may be?

Thanks,

Is there any text to your "VBScript runtime error"? That code looks similar to the code in this tip (PDF)---http://www.acresso.com/webdocuments/PDF/disable.pdf---so no obvious issues there...

Yes the VBScript error looks like this:

Error 2738. Could not access VBScript run time for custom action .

That is all that the error stated....

So could this mean that the machine that it is running on does not have a VBScript run time engine or is this some other issue.

Have only seen this on the one machine at the moment, but then the we only just released a little while ago.

Thanks,
