Introduction

The Sentinel HASP key that is used as software protection for the Pro-Router uses system drivers to interface between the application and the plug-in key. Sometimes if there are problems with the drivers it is necessary to uninstall the drivers and start again.

Although there are automatic removal tools, there may be situations where a complete manual removal is necessary. The procedure for this is documented below.

To check if the driver is at fault, run the utility "HaspID.exe" which should be in the main program folder which can be accessed by right clicking on an Easy-PC shortcut and using 'Open file location'; or it can be downloaded from [Technical], [Tools].

Removal Procedure

Disconnect the local HASP key.

Make sure you are logged in as an administrator.

To make sure no old drivers exist, right click on the Easy-PC shortcut and use "Open file location".  A File Explorer window will open.

Confirm that "Haspdinst.exe"' is present (it should be in all recent installations).

Open a command prompt using 'Run as administrator' mode.  If unsure, type "cmd" in the search bar which will take you to a page from which you can open it.

Click on the top bar of the File Explorer window, which will highlight the path and allow you to copy it (use <Ctrl+C>)

On the command line type "cd<space>" then use <Ctrl+V> to paste the folder.  Press <Enter>.

Again from the command line, run haspdinst.exe<space>-r<space>-kp<space>-fss<space>-purge (haspdinst.exe -r -kp -fss -purge), in order to remove any old installations.

Go to "C:\Program Files\Common Files" and delete any folders marked "Aladdin Shared" or "Sentinel Shared" if present.

Error while installing driver

From "add/remove programs", remove any HASP components

Go to Windows Services (or use Task Manager) and stop any service which starts with "Hasp", or "HLServer"

Erase any "aks*.*" files, "hardlock.sys" and "haspnt.sys" from "c:\windows\system32\drivers" (or equivalent folder for your version of Windows).

Remove drivers as described above.

Reinstalling the driver

Either:

Run Haspusersetup.exe from within the copy of File Explorer opened earlier.

Or:

From the command prompt as above, type 'haspdinst.exe<space>-i then <Enter>.

Whichever option is used, insert the key then run HaspID.exe again to check that the key number appears under 'Serial number'.
