[SAP B1] Error in installing SAP B1 on a virtual system

Hello,

I'm trying to install SAP B1 on a virtual system, not my local laptop.

An error message keeps occuring while License Authentication is processed.

It says "Authentication against the specified License Server has failed. Check your Site User password."

I've already checked the password.. (has typed a correct password.)

If experts let me know how to solve this problem, I would really appreciate that.

Thanks

Wonuk Jeon
