Parallels 8 and Windows 8 installation error messages

Hello,

I recently installed Windows 8 over Windows 7 within Parallels 7 and then upgraded to Parallels 8.

1. I am now receiving the following error message:

Cisco System VPN Client 5.0.7.0290. Error 1706. No valid source could be found for product Cisco Systems VPN Client 5.0.7.0290. Windows Installer cannot continue.

Does this error message mean I need to download and reinstall Cisco System VPN Client 5.0.7.0290?

2. I also noticed that my Dropbox account is no longer connected to My Documents/Windows Explorer. To reconnect Dropbox, should I reinstall Dropbox or is there another method for reconnecting?

I have reinstalled Parallels Tools in WIndows 8.

Thanks,
Ben
