    After updating my Dell Optiplex 330 to BIOS A11 with SLIC 2.1 added, I attempted to activate Windows 7. I followed this method:


    I have installed the Dell certificate with slmgr. I have verified the SLIC 2.1 table is installed via SLIC_Toolkit, which shows “Dump OK ! ( DELLB9K_V2.1 )”. When I load the Dell certificate in SLIC_Toolkit, I get a green light on the key. Everything looks good, right?

    I then tried activating with the key shown in SLIC_Toolkit, and also one found at a link at the site listed above. Both times the activation failed, saying the key was not valid to activate Windows. I then tried Anytime Upgrade with the Dell Windows 7 Ultimate key, which also failed to activate.

    I'm at a loss, as the directions were very straightforward and it appeared that everything went successfully... except the most important last step. Any ideas where to go from here to get this machine activated?

    2 things:

    1. I thought the whole point of OEM BIOS modding was so you could avoid needing loaders. I'd prefer to only use a loader as an absolute last resort.
    2. When I look in the BIOS, the service tag shows as blank. Could this cause a problem with activation? I thought I read somewhere that you may need to change your service tag to fix activation issues on Dell's.

    1. Daz's loader only installs correct cert & key if valid SLIC 2.x is there.
    2. Please post a screenshot of SLIC Toolkit advanced tab.
