How to upgrade/downgrade vb script version on windows server 2003 SP2

hi,

I'm facing issue with my VB script on my windows 2003 server. Current VB script version is - 5.6.0.8852 and I want this to upgrade to 5.7.6002.23292. Kindly share me the steps to perform this.

And also I want to revert back it if something goes wrong. So kindly share me the steps to upgrade/downgrade VBscript version on windows server 2003 sp2.

Thanks in advance!
