In some cases, the installation for SONAR Home Studio 7 and GT Pro 4 does not add the default VST plug-in folder path. If you do not see the included VST plug-ins (such as Amplitube or Studio Instruments) when inserting an effect or synth, here are the steps you can take:
 

1. Go to OPTIONS | GLOBAL | VST PLUG-INS
    
2. If no path was listed and your VST plug-ins were installed to the default location, click the [ADD] button to add the folder path below:
   C:\Program Files\Cakewalk\Vstplugins
   
   Note for x64 Users: If you use Windows Vista x64 or Win7 x64, add this path instead:
   C:\Program Files (x86)\Cakewalk\Vstplugins
    
3. If you do not know where your new VST Plug-Ins are located, then we recommend re-installing the plug-ins and noting the default VST folder destination. You can re-install any of your VST plug-ins by re-inserting your installation disc and choosing to do a selective installation, leaving only the VST Plug-in in question checked on your installation list.
    
4. Once you have added the correct path, check the boxes "Re-scan Existing" and "Re-scan Failed"
    
5. Click the [Scan] button.
