I've found a beginning of solution by replacing the default printer ( HP DeskJet 660C ) by an other (IBM 4216). I think it's a problem with HP
driver.

Suggestion by: Bertil Isberg
This could be caused by an incorrect installation of Paradox. If Paradox was installed by a user account instead of by Administrator, some registry
keys has not been registered for the Default user. You have two options.
- Uninstall and reinstall as Administrator
- Login as a user for which the problem doesn't occur. Export the registry keys
HKEY_CURRENT_USER\Software\Corel\Paradox\11 and
HKEY_CURRENT_USER\Software\Corel\Paradox\11.0
Eventually run these registry files when logged in as the failing user.
