I used it, had similar issues and it fixed the problem!
In short do the following:
1. Click Start, and then click Run.
2. In the Open box, type regsvr32 jscript.dll, and then click OK.
3. Click OK.
4. Click Start, and then click Run.
5. In the Open box, type regsvr32 vbscript.dll, and then click OK.

Good luck!
