This is a crack by R2R that first installs Omnishpere 2.0.3d, which is later updated to 2.6.1e,
and using the standalone update can be updated to 2.8.4d
Do NOT move the installers or .iso files out of their respective folders. The crack relies on the folder hierarchy.
Please disable your antivirus(es) before even starting to download.
The crack contains both Windows and Mac installers.

    Step 1: Run the installer (Omnisphere 2 Installer.exe/.pkg)

    Step 2: Select all the .iso files, right-click and mount

    Step 2.1*: You can also mount them one by one when the installer requests it.

    Step 3: Run the Data Updater (Omnisphere 2 Data Updater.exe/Omnisphere_Data_Updater.pkg)

    Step 3.1*: If you use Trilian/Moog Tribute, run the library patchers in their folders.

    Step 4*: Run the Update (Omnisphere Software Update.exe/.pkg)

    Step 5: If you updated to 2.6.1e, run the KeyGen inside the Omnisphere Update folder, otherwise
    use the Keygen in the Crack folder

    Step 6: Click Patch and select all your Omnisphere .dll's, like:

    C:\Program Files\Steinberg\VSTPlugins\Omnisphere.dll
    C:\Program Files (x86)\Steinberg\VSTPlugins\Omnisphere.dll

    Step 7: Open Omnisphere in any host and copy the challenge code into the KeyGen, click Generate and paste the response code back into Omnisphere.

    An easier approach, that also prevents decoding issues is to change the authorization link domain from "" to "", from where you can copy the code | Made by patricko#6923

    Step 7.1*: If Omnishpere crashes without activating, just retry Step 7.

    Step 8*: To update to 2.8.4d, run the provided updater and replace the installed files with ones in the VST folder.

    C:\ProgramData\Spectrasonics\plug-ins\64bit (The ProgramData folder is hidden by default in Windows)
    VST3 Plug-In: C:\Program Files\Common Files\VST3
    VST2 Plug-In: C:\Program Files\Steinberg\vstplugins (Depending on the DAW you are using, this path may be different. Look carefully where the installer will offer to install the VST2 file)
