Sincrosoft error when installing cubase 4

I use Windows 7 64 bit. I try to install Cubase 4 and i received an error from Syncrosoft “There are other activated processes wich disturb…” I have try to reboot, install newer Syncrosoft software. No result. Any solutions ?

Run as Administrator.

Hello. I have already try that solution. Thank’s

What is the rest of the error message?

There are other activated processes which disturb the installation process.
Please restart the computer and repeat the installation.

Try turning off DEP.

What is DEP ?

Data Execution Prevention, Google is your friend.

Oh also, supposedly there’s a 64bit installer for e-licenser. Check at the site.

Thank’s for your help but it don’t work.
