Thanks for your answer Randy
-TESTINSTALL is added to the License key as it i supposed to be. But when the install is processed at the new location using a subdomain. This all happens during the initial install just after enter LICENSE KEY-TESTINSTALL it tells me:
A test installation has already been activated for this license key. Your license key entitles you to one test installation only.
The folder and all files from previous location were removed from the server prior to the new install
NVM Mind installed in same folder then placed the correct subdomain into the setup and install is processing
