If you are getting trouble installing Pinnacle “Dazzle” USB video capture device driver with model DVC100 on Windows 7 and your laptop is HP Pavilion DV6, getting error: Error 1719. The Windows Installer Service could not be accessed. This can occur if the Windows Installer not correctly installed. Contact your support personnel for assistance. Here’s the fix:

Some causes that might be blocking you from installing Pinnacle’s USB video capture device driver with model DVC100 are: incorrect registry settings and value, corrupted windows files (usually msiexec.exe), corrupted installation files.
You can try using our workaround for XP compatibility below:
- Open a command prompt (search for CMD in the search box, right click and run as Administrator)
- Type SFC/SCANNOW when the CMD window opens.
- Once it is completed, type:
msiexec /unreg
to unregister the exe, after that type
msiexec /regserver
to register it again - Open up regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSIServer
- Look for imagePath value on the right pane and change the value to the location of msiexec.exe on your laptop
Restart and hopefully this workaround works.
