If you see this, I bet you should check your network cards. It's likely the RSA token tool is confused by a new network card or something you installed. I have a feeling it uses the MAC address of the card for some sort of identification purpose.

In my case, I had added a 3G AT&T USBConnect wireless card. When I unplugged it, immediately the tool started running again.

I would say that you should give an Admin rights to the user.

Reinstalling didn't work. I cleared the temp files: Start > Run > TEMP (and %TEMP%) before this worked.

if using windows 7 choose to run as XP SP3.

The issue I had was very specific to running aventail with software token on oracle virtualbox. The mac id of the network card is apparently involved in the token config so you cant use a nat virtual interface - you have to use a bridged adapter.

I am having windows 7 homeprimum laptop. i installed RSA software..it was working fine. but when i reinstalled it for some reason..it started giving above problem.. I tried to run as administrator as well as IN XP mode.. doesnt work for me. any other suggestion. Its not working in other local profile as well.. Pls suggest work around

I'm running XP SP3 and have had same problem - re-install didn't worked - same problem. I finally solved it by installing another (possibly newer) version of the RSA SecurID - version 3.0.6 [251] It started to work again afterwards.

Forgot to add that I didn't add or remove any new network cards. Make sure that you kill the securID.exe process which will prevent the complete un-install if you get the error above.

I had the above issue after moving my laptop hard drive (windows 7 64 bit) to a newer laptop that had a different nic on it. I resolved simply by removing the SoftwareTokens.DB from the installation dir of the RSA tool. Then rerun and re-import your *.sdtid.

It also may cause by computer's hostname change. i choose a new hostname for my computer and then rsa broken, when i change hostname back again it worked.

To repair TKN library error. Search for the RSA file and delete 'Software Token.DB'. Make sure that you have a seed file to import back to your RSA software. Hope it helps :D

delete "SoftwareTokens.DB" in the following location C:\Users\[*** Your User ***]\AppData\Local\VirtualStore\Program Files (x86)\RSA Security\RSA SecurID Software Token\

Cut or delete filename SoftwareTokens (db) from the directory C:Program Files (x86)RSA SecurityRSA SecurID Software Token

user123459 Aug 11, 2011

Remove the program and deleted the RSA folder from C:Users[*** Your User ***]AppDataLocalRSA Security. Reinstall the RSA software.

Somehow, RSA token has to be saved from Microsoft Outlook. Then you can import the token. I got this advice from RSA support team, and it worked. You need to install out look and try importing

This is right. Yaswanth Midathala
