If you are upgrading from a prior version of SLIM Suite 8.1, there should be a readme.txt file in your Tools81 directory. The default path for this directory is c:/Program Files(x86)/QSM/Tools81, but you can also find it by right clicking any SLIM 81 application shortcut and looking at the shortcut properties.  In most instances, you will not need this information to upgrade to the latest release of version 8.1.

Your activation code, installation instructions, and license information can also be found in your version 8.1 QSM license or upgrade email.

If you need help locating these documents, please contact your software administrator or email QSM support.
