Error: 'Can't find script engine VBScript' when installing or upgrading GFI FaxMaker ( ONLY)

Author: Luis Fernandes Updated

Answer

PROBLEM

Installing or upgrading of FaxMaker fails with the following error:

Can't find script engine VBScript

ENVIRONMENT

  • GFI FaxMaker
  • All Supported Environments

SOLUTION

STEP 1 - CHECK THE REGISTRY

Start regedit.exe and check the following keys:

32bit:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}
  • The ImprocServer32 subkey should point to C:\Windows\system32\vbscript.dll
64bit:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}
  • The ImprocServer32 subkey should point to C:\Windows\system32\vbscript.dll
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Wow6432Node\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}
  • The ImprocServer32 subkey should point to C:\Windows\SysWOW64\vbscript.dll
If these subkeys point to other files (e.g. dll-files from anti-virus software), it indicates that the software hooked into the VB script engine.

STEP 2 - POSSIBLE SOLUTIONS
  1. Uninstall the conflicting anti-virus software
  2. Re-register Windows' own VB script engine:
IMPORTANT: Ensure to create a system backup before making any changes.
  1. Start regedit.exe
  2. Export the registry keys listed above into a reg-file
  3. Delete the registry keys listed above
  4. Hit the keys <WINDOWS>-R and run the following commands depending on the bitness of the OS:
  • 32bit OS:
    • %WINDIR%\system32\cmd.exe
    • regsvr32.exe vbscript.dll
  • 64bit OS:
    • %WINDIR%\SysWOW64\cmd.exe
    • regsvr32.exe vbscript.dll

CAUSE

The installer fails to run VB scripts as the VB script engine is not working properly. The most likely cause is anti-virus software hooking into the VB script engine or it being corrupted
