Most computer musicians who use the popular FL Studio sequencer (formerly Fruity Loops) to create their compositions and realize their creative ideas often ask questions about how to activate FL Studio 12 or other modifications of the application so that they can use absolutely all the features of the program without a constant reminder of the end of the trial period. To perform such an operation, there are several basic methods, but it all depends on how exactly the program was obtained and how legal the method chosen by the user will be.
How to activate FL Studio 12 or any other officially purchased version of the sequencer?
First, consider the option of unlocking the program for cases when it was purchased completelyofficially. How to activate FL Studio 12? There are two options for this, which are available for use when opening the main settings window with a transition to the About tab.

Here you can either use a registered account and click the Unlock with account button, or specify the license file that comes directly with the purchase of the application, for which you will need to click the Unlock with file button. However, given that the official release of this virtual sequencer is quite expensive by our standards, users of the post-Soviet space are in no hurry to buy it, but prefer, in a sense, illegal methods to unlock the program.
Unofficial activation
Today, on various sites in Runet, you can find versions of FL Studio that come with a "tablet". Most often, these are unofficial builds from the notorious group of R2R crackers. Speaking about how to activate FL Studio 12 or any other version of the sequencer when downloading just such distributions, we can also suggest using two main methods that directly depend on the content of the downloaded archive.

Firstly, sometimes an additional utility in the form of a key generator (KeyGen) is supplied with the installer, and secondly, recently all activation comes down to running the accompanying registry file on behalf of the administrator, followed by confirmation of the merger and inclusion in registrychanges. In such ways, not only the main application is unlocked, but also all the "native" plug-ins of the program that could be loaded from other sources. It is clear that in this case the FL Studio 12 activation key is not required. Unlock information is entered into the system registry automatically.
How to install plugins in FL Studio 12 and activate them if they don't work?
As for installing plug-ins of other formats (VST, AAX, DX, etc.), it's not so easy either. We most often use all the same generators that either create the keys themselves, which must be entered in special fields of non-activated instruments and effects, or generate separate license files, links to which must be selected when unlocking plugins.
It is not always advisable to install the instruments and effects themselves in the default folders selected by programs.

You can also specify your own directories, however, using the plugin management directly in the sequencer, you need to add such directories to the list where the application will look for instruments and effects yourself.
But most of the problems are usually associated with the inoperability of the libraries of the popular Kontakt sampler. Even after its initial activation, some libraries are still blocked.

In this case, it is not necessary to unlock the libraries themselves, but it is enough to use reactivationthe sampler itself. By the way, you can even find generators on the Internet that allow you to activate absolutely all known plug-ins from Native Instruments in automatic mode.
Speaking about how to activate FL Studio 12 and additional synth modules or effects that can work through the host program, do not forget that many VST instruments can initially be downloaded as cracked versions, and the user after installing them it will be enough just to replace the source files of EXE (for Standalone versions) and DLL (for VST-format) formats with the corresponding hacked components.
