Actually this is what I've done earlier.. and as said i read all posts about this issue including the tutorial; nevertheless i still the same issue but now i know why so i'll share it.
I was using Orbit as a download manager for the driver packs; what i haven't noticed that it changed the ext. of the files from 7z to .zip which sure it shouldn't

Topic: DriverPacks greyed out (4 replies, posted in Feedback and Support - DriverPacks Base)
Hello all
First I'd liek to say thanks for the wonderfull tool, and for the effort you are making here to help us the users.
Now i've went through ALL the posts before writing about this issue, and there can not be seem solution. Driver Base still can not seem to locate driver packs located under the folder, all are greyed out non selectable; plus i've messed with different settings, changed the DP installaion dir, my windows cd files folder & name.. No luck! i have things as follow:
DriverPacks BASE 7.05.2
config: inst. platform: disc, method1 for slipstream, KTD disabled.
H:\2003 (my windows server 2003, 32 bit, files) DP Base detects OK (tried with SP2 slipstreamed, also out of the box without any sp)
H:\DriverPacksBASE (DP base files)
H:\DriverPacksBASE\DriverPacks (folder of the driver packs i've downloaded, and kept zipped, actually tried unzipping as well, no luck)
I still can not figure out why it can not detect the DPacks; I'm *assuming* it's something to do with DP Base folder locations (not the driver packs folder), or the namings... any ideas?
