Hi folks!   I haven't been here in quite awhile [because I got all my problems solved here!].  But of course there is always one more:   I am attempting to install Win7 on a Lenovo W540 w/8GB and the 2.70 CPU.  I can run 8.1 on it fine, and I have also installed Vista [although many driver problems, but I still got it up enough to have it proclaim "genuine software".   I can install the product key [that matches the Windows version] fine.  But I cannot install the cert file   LENOVO_V2.1_Cert.XRM-MS   and get the error code 0x00000BBA   The spool file was not found.   Is this somehow related to the fact that the Win8/8.1 key is built into the BIOS?   Do I need a[n even] new[er] Cert file?   All else is fine, but only got about 3 weeks more to activate.   Any help appreciated.
