Hello MDLers, I recently modded a Dimension 2400 bios and confirmed that SLIC 2.1 was present with SLICDumpToolkit. I used the OEM SLP key after installing 7 Professional SP1, the MS release. The key is invalid for activation. Does the OEM SLP offline activation only take place if you use the non-SP1, orignial RTM release? Is there anything I can do short of using a loader, or reinstalling to get a key to activate the system.
