NOTE: A text version of the license agreement is available in a file named "license.txt" in the folder where CSS HTML Validator is installed.
Q: Can I purchase a single license and install it on both my home and work computer (or desktop and notebook)?
A: Yes, but only if you are the only user of both computers and only if you do not use both installs at the same time, otherwise you will need more than one license.
Q: Can I transfer or move my license to another computer?
A: Yes. Please see the Transfer or Move License topic.
Q: Can I use a single license for multiple websites/domains?
A: Yes. Licenses are not limited by number of websites/domains.
Q: Can I give or sell my previous license to someone else after upgrading?
A: No. If you upgrade a license, then that license is upgraded and does not become a separate, individual license (another license is not created); only one license still exists.
Q: Can I distribute CSS HTML Validator?
A: Provided no fee is charged, you may distribute the setup program for any trial version in its unmodified form. However, any version that is only for registered users (this includes all versions that you can enter a license key into) MUST NOT be distributed.

--- LICENSE TO USE ---
Your license is non-exclusive.
You may not sell, rent, or lease the software to others without the prior express, written permission of AI Internet Solutions LLC.
You may make a reasonable number of copies of any version of the software for backup and archival purposes.
One copy of the trial version of CSS HTML Validator Professional may be used by a single person and on a single computer for evaluation purposes without charge for 30 days or 200 validations, whichever comes first. Reinstalling the same version, or a different version of CSS HTML Validator Professional may or may not restart the trial license.
One license of the registered version of CSS HTML Validator Home, Professional, or Enterprise may be:
(a) used by a single person who uses the software personally on one or more computers and is the only user of all the computers, or
(b) installed on a single workstation used non-simultaneously by multiple people.
In the case of (a) above, if one license is installed on more than one computer, then only one installation may be used at a time.
You may access the registered version of CSS HTML Validator Home, Professional, or Enterprise remotely over a network, provided that you have obtained enough licenses to cover the total number of workstations that will use the software over the network. For example, if the software will be accessed from five workstations, then five or more licenses (and not three) are required, even if only a maximum of three of those workstations will run the software at any one time. However, if you have more than ten (10) licenses and you have software that allows you to run CSS HTML Validator from a network and that software also manages the number of concurrent users to make sure it is limited to the number of licenses you have, then you only need the number of licenses that are allowed to run concurrently (minimum of ten (10) licenses).
If you are a registered user, then you are entitled to use this product for your own use.
You must not give away your registration key. Doing so will result in an infringement of copyright. AI Internet Solutions LLC retains the right of claims for compensation in respect of damage which occurred by your giving away the registration code. This claim shall also extend to all costs which AI Internet Solutions LLC incurs in defending itself.
