VBScript cant be started by Host Monitor

Good afternoon:

OS: 2008 R2
Host Monitor: Latest version

We are in the process of migrating Host Monitor to a new Server, however im having problems with Host Monitor executing VBscripts that used to work on the old machine (Right now we cant migrate completely to the new one), said scripts used to call a program called Imacros that automatized most of our web monitoring.

I fixed some registry values that wouldnt let me run the scripts even from the Command line, so right now you can launch the scripts with no problem from the explorer and/or Command line and they launch Imacros with no problem, however everytime i try to launch said scripts from Host Monitor i get the following error "A script engine for the specified language cannot be created). I even disabled the UAC because i thought it was a problem with the authentication, however i still cant run any scripts from HM. I have no other problem with the other types of tests, its just the Active Scripts tests that I cant run. I even reinstalled Host Monitor but no luck yet.

Google suggests this problem caused by incorrect uninstallation McAfee antivirus.
Did you have McAfee and then uninstalled it?

What values set for the following registry keys?
HKLM\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32
HKLM\SOFTWARE\Classes\Wow6432Node\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32

Regards
Alex

Right now the McAffe antivirus has not been uninstalled. Should I proceed with uninstallation?

The strings values are as they go in order:

C:\Windows\system32\vbscript.dll

C:\Program Files (x86)\Common Files\McAfee\SystemCore\ScriptSn.20131015152710.dll

I think i also changed some strings that werent those...

You may try the following steps befor Uninstalling McAfee:
1. Open a command prompt in elevated mode (run as administrator).
2. Type "regsvr32 vbscript.dll"
3. Open regedit and verify that HKLM\SOFTWARE\Wow6432Node\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32 is pointing to vbscript.dll
4. Chack if the same key exist in HKCU hive. If it exists, please delete whole HKCU\SOFTWARE\Wow6432Node\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8} tree.

Please note McAfee may rewrite this key. In such case it's better to uninstall McAfee.

Thanks, that seems to do the trick.

McAffee is such a headache.
