[TYPO3] **Install Tool is locked.**

[Pierre M]

ON a fresh installation I get the Message:

"The Install Tool is locked.

*Fix:* Create a file typo3conf/ENABLE_INSTALL_TOOL
This file may simply be empty.

For security reasons, it is highly recommended to rename
or delete the file after the operation is finished."
------------------------------
I've tried to create a simple txt file and upload it to the *typo3conf/ *
directory

...not working

the installation was done inside my control pannel via hsphere plugins
version is 4.13
Can any one help...?
