If you're using the solution below and the command prompt says something like "The system could not find the specified path" then you have to do step 4 differently if your System 32 and SysWOW64 are not together. I wouldn't move them together so instead type "cd C:/Windows/SysWOW64" without quotes and continue on. A prompt will say it has succeeded for both steps if done correctly. Hope I helped.
Windows 7/8 x64 users- you will need to run command prompt as administrater for this to work.
Move your mouse pointer to the very bottom left of the screen... then right click and choose
- Command Prompt(admin)
Then register the dll's...
type - cd C:WindowsSysWOW64 - hit enter
type - regsvr32 dx7vb.dll - hit enter
type - regsvr32 dx8vb.dll - hit enter
