How to get a new license file for a old product?

If the product is too old there are only two ways to handle this.
You need to renew SSA or upgrade the product version or if the version support the use of USB Locks then we suggest you to use a hardware lock.

Once a license is 5 versions (6 -7 years) or older than the current license today (e.g. WI 17, 16, 15, 14, 13 or older) there is not more normal support for re-licensing.
