Can't find script engine vbscript error at login

[Former Member]

Hi,

few users reported that "Can't find script engine vbscript" error when they login in each time. Verified in blogs and found the below solution.

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

HKEY_CLASSES_ROOT\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32

1. Right-click this key and select "Permissions..."
2. Select the "Administrators" group and click the check-box for Allow "Full Control"
3. 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

HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32

1. Right-click this key and select "Permissions..."
2. Select the "Administrators" group and click the check-box for Allow "Full Control"
3. 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

Why Mcafee Causes the issue, can anyone explain and why this error occurs

Hi,

according to McAfee, this is due to an uninstall/upgrade bug, see KB86138.
