1. Try the below and see what transpires:
Are you attempting to install a program?
Look for MSCOMNCTL.OCX in the following: C:\Windows\SysWOW64 directory
Right click on Command Prompt and select Run As Administrator
Type the following
CD C:\Windows\SysWOW64 directory
You should get a message "DllRegisterServer in mscomctl.ocx succeeded"
Proceed with the installation
2. MSCOMCTL.OCX is a set of 32-bit controls that were provided with the Microsoft Visual Basic 6.0 programming environment.
If you go to your C:\Windows\SysWOW64 directory and see MSCOMCTL.OCX already in there then try this:
Browse to your command prompt shortcut via Start-->All Programs-->Accessories-->Command Prompt. Right click on that Command Prompt icon and choose to Run as administrator. Click Yes to tell UAC you really want to run it.
When the black window opens with your command prompt, type this in:
cd<push spacebar>C:\Windows\SysWOW64 <push Enter key>
The prompt should change to: C:\Windows\SysWOW64
regsvr32<push spacebar>mscomctl.ocx <push Enter key>
If you get a Window that pops up and says, "DllRegisterServer in mscomctl.ocx succeeded" then click OK and try the frontend install again.
If you are not familiar/comfortable with this, you may need to get someone to help you with it as you may have to download the OCX from the internet. Normally, if you reinstall spooky it might work.
