You should use forum's search  http://bbs.pediy.com/showthread.php?t=71599&highlight=crypkey+installation+password

Thanks,

I saw it already and I've already tried it (with success ).  

The password you linked is the one for SDK (fortunately it's the same for the SKG) .

Regards!

I can't use SKG to generate sitekey(I have the correct masterkey & userkey)
WHY??

Because u havent configured it for
your company and licenced it for your
company.

Lets say we use a company/key  details from
this thread:(for illustration purposes)

http://bbs.pediy.com/showthread.php?t=62414&page=13&highlight=crypkey

so we have the following info's
sitecode  : C233 C2C1 74E3 BDF8 03
userkey   : F4DF1E5DF52BC01A91413849BC

Before u licence the SDK u must edit the ini file
ie SKW ini file in program folder (SDK 7.1.03)

using options=1-16 and level bit 65535 all boxes are ticked ( !)
So then u paste this into your ini file.

Then u would start your crypkey SDK and licence using this script
from : http://bbs.pediy.com/showthread.php?t=71599&

#Default Script (ckInfo)
ScriptName=CrypKey Site Key Generator 7.1
Action=CreateSiteKey
SiteCode=**** **** **** **** **               ---- from the SDK
UserKey=DAA7 6B07 0237 5AF5 24
NumberOfLicences=1
NetworkLicence=no
AddToExistingLicence=no
EasyLicence=no
LicenceDuration=unlimited
KeyOptions=14
KeyLevel=464                   ------------------------  here is the catch that gets
                                                                        everyone ; the level must= your
                                                                        company number.

Now this configuration will only make licence keys for
company number 464 and product # 1 .

When u get your head around this ; there is other
tricks to learn with the SDK
