Installation failure with Error 2744 or Error 1722

If the installation of the WAsP Licencing System fails, and shows you a message box with error number 2744 or 1722, then it's probably because your machine already has the device drivers for HASP dongles installed, and the installation cannot replace them. This is how the error messages may look like:

Please try the following – or contact your system administrator and ask him/her to try it for you. Don't proceed unless you're confident that you can perform all these steps. If in doubt, then please contact waspsupport@risoe.dk for more help.

• Check that you are logged in as Administrator
• Open the "Add or Remove Programs" window in the Control Panel (under Settings on the main menu)
• Look for an entry called HASP Device Driver
• Remove the HASP device driver
• Remove any connected HASP dongles (see the picture below)
• Run the WAsP installation again
• When the WAsP installation has finished, re-connect the removed HASP dongles. You may also want to re-install your HASP drivers again to ensure that you have the latest version. If you don't have the originally downloaded file, you can get it again from the Aladdin web-pages
