Can't find script engine "VBScript" for script.

My Dell also had McAfee in the mentioned registry key. McAfee has a user uninstall utility that will remove and restore the registry keys. It worked for me....if you trust McAfee.

I've also been having this problem and was grateful for the advice on this thread, particularly auggy's post. McAfee was the culprit for me also. A few posters mentioned that they needed to set permissions on this key before they could edit it, it was the same for me. In addition, I had a unique issue not covered in the thread, where a 32-bit app (on a 64-bit os) was trying to run a vb-script and it needed an extra key tweak for this this to work.

So thought I'd summarise an explicit list of steps that encompasses everything I garnered from this thread, in addition to my extra hurdles. I'm not sure if base64 encoded screenshots will work here, but I've tried to add them in too...

1. Open regedit as administrator
2. Browse to the following key:

HKEY_CLASSES_ROOT\CLSID{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32 3. Right-click this key and select "Permissions..."

4. Select the "Administrators" group and click the check-box for Allow "Full Control"

5. Edit the "(Default)" key's value and change it:

FROM: C:\Program Files\Common Files\McAfee\SystemCore\ScriptSn.20140819031109.dll

TO: C:\Windows\system32\vbscript.dll 6. Now browse to the following key for 32-bit apps:

HKEY_CLASSES_ROOT\Wow6432Node\CLSID{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32 7. Right-click this key and select "Permissions..." 8. Select the "Administrators" group and click the check-box for Allow "Full Control" 9. Edit the "(Default)" key's value and change it:

FROM: C:\Program Files (x86)\Common Files\McAfee\SystemCore\ScriptSn.20140819031109.dll

TO: C:\Windows\system32\vbscript.dll

Now vb-scripts will run fine, whether triggered from a 64-bit or 32-bit process...

If McAfee is involved at all, then usually simply running the McAfee MCPR tool will clear the problem completely.

Download the McAfee removal tool from:

http://download.mcafee.com/products/licensed/cust\_support\_patches/MCPR.exe

Click Save, and save the file to a folder on your computer.

Navigate to the folder where you saved the file.

right-click on MCPR.exe and select 'Run as Administrator'  to run the removal tool.

when complete, reboot.

A lot simpler and less dangerous than messing in the registry! ;)

Cheers Noel, but completely removing McAfee isn't an option for me in my work environment, McAfee is a mandatory install.

So for those lucky enough to un-install McAfee, the MCPR option sounds great.

But for those people that have to live with McAfee, unfortunately the messy registry tweaks are our only option I know of...

Unless ofcourse McAfee look into the issue and resolve it, which would be very nice too :) Well, I guess they will eventually, once someone chases them up enough about it.

I changed the second file to the right "Data", but then it said, "Cannot Edit: Error writing the value's new contents". PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
