Solution 2 From Others

Because I know there are some of you out there who are a visual like me, I thought I’d pass along David and Niklas’ solutions and add a few screen shots.  These solutions assume you are running a 64 bit Windows operating system.

Step 1:  Open an elevated command prompt. 

Start Menu Run As Administrator

  • Go to the Windows Start Orb > All Programs > Accessories and find the Command prompt.

  • Right-click on the Command Prompt icon and select Run as administrator.

  • The Command Prompt will open with elevated privileges

Step 2. Navigate to the SysWOW64 directory

CMD SysWorDir

The easiest way to do navigate to the SysWOW64 directory is with the following command:

cd C:\Windows\SysWOW64

The example above assumes that the C drive is where Windows is installed.




Step 3.  Unregister the Hotarea.ocx dll

 Type regsvr32 /u Hotarea.ocx and press enterCMD-Unreg

Click OK when the information Window displays DllUnregisterServer in Hotarea.ocx succeeded.








Step 4.  Register the Hotarea.ocx dll


Type regsvr32  Hotarea.ocx and press enter

notice the /u switch is gone

Click OK when the information Window displays DllRegisterServer in Hotarea.ocx succeeded.




Step 5 Launch the MeasureUp Test Engine and start the test
