When I executed a simple CA of vbscript (the code is 'Stored directly in the custom action'), I got error 1720. Here is the code:
Dim WshShell, bKey
set WshShell = WScript.CreateObject("WScript.Shell")

bKey = WshShell.RegRead("HKLM\Software\Myproduct\InstallDir")

if Len(bKey)>1 then
Property("INSTALLDIR") = bKey
end if

It seems once I have WScript.CreateObject, it will produce the error. Does that mean that there is only restricted vbscript can be used for CA in Basic project? How can I create WScript objects (Shell, Network, etc.) in vbscript code?

Use CreateObject instead of WScript.CreateObject

No, still got the same error. The problem is on RegRead and RegWrite methods. It's either the object was not created properly or the object was created but the methods couldn't be invoked (not supported by Developer7?).
If I block the RegRead and RegWrite call (the script just do nothing except calling creatobject), the error is gone.

If you try to read a non-existing key, RegRead will fail, which will result in 1720. Test your VBScript standalone, remember to comment out all references to Session object. It is easier to debug while running a VBScript standalone.
