Question about VBS

I have a question concerning batch files and VBScripting. I have searched and searched the Internet including Microsoft. I am trying to either evoke a batch file from a vbscript or a vbscript from a batch file. I have used both execute and call to no avail. I would prefer to have just one file. I am trying to uninstall all versions of acrobat reader in a windows 2000 environment so that all workstation can be at 6.0.2. I can not seem to get one file to do an uninstall of all versions.
Thank you in advance
Michael
