Saral TDS Professional error 1401

Hello all,
Recently I tried to install the employee tax computing software saral TDS professional but I couldn’t complete the installation successfully. It ended up in the following error on the screen:

The error says:
Error 1401: Could not create key “HKEY_USERSS-1-5-21-1417001333-261478967-725345543-1005SoftwareClasses”. Verify that you have sufficient access to that key.
Can anyone please shed some light on how to solve this problem? I'll be really grateful.
Waiting for your replies.
Kindest regards.
