Windows 7 - CScript Error: Can't find script engine "VBScript" -alternate solution

I just came across this error in troubleshooting an MGADiag report to solve a non-genuine message on a Vista computer.
It took me a large amount of searching to find the right answer to it - so I thought I'd post my solution here in the hope that it gets a little easier to find for others in the same position


CScript Error: Can't find script engine "VBScript" for script "C:\Windows\system32\slmgr.vbs".

This was preventing the Software Licensing Service in Vista doing what it needs to - and consequently giving rise to the non-genuine message, despite a perfectly genuine install.

The conventional response is to re-register the dll using
regsvr32 vbscript.dll

This works fine in many instances - but in this case, although the registration gave rise to the 'succeeded' message, as it should (thereby showing that the dll was present), there was no change in the response from MGADiag.

The user had been using a registry cleaner - and this was in another forum, and she wasn't the world's most savvy user. All attempts to get her to properly follow reg query instructions failed.

Eventually, I got a clue to the problem from an obscure blog, which mentioned that some AV's blocked a particular registry entry, by substituting their own dll for the vbscript one.

The penny dropped at last - so I created a small reg file to put the default entry there instead.

with fingers and toes crossed, I sent her instructions to download and merge the file.
.....and it worked! The thread was by that time 45 long, with just the two of us in it.
Huge sighs of relief all round, and she's promised never to use a registry cleaner again.
So two victories for the price of one.

Not a bad result [edit] - and yes, it should also work in Windows 7 and XP [/edit]

(if anyone finds a better forum to put this in, please feel free to do so!)

Endured the registration prossess just so I copuld say "thank you". Your registry fix brought much joy. More than six months of searching for a fix ended when I found this registry merge. Thank you muchly!
