Hello,
When I right click on individual app then choose delete, for example: PDFXchangeViewer. It's gone from liberkey. I check the C:\LiberKey\Apps. I can see PDFXchangeViewer is still in there.
How do I complete remove individual apps from liberkey and from my computer?
Thank you.

Hello,

Liberkey Tools
Manage portable applications

1 more question. Am I supposed to install liberkey on my computer drive or on an portable drive?

Wherever you want.
Internal or external drive, USB Flash Drives, etc. ...

Does it mean that I'm not supported to install it on the Local Disk? I'm a noob.

Yes you can use it on your local disk without problem.
