Error: Unable to install an application because an application with the same identity is already installed

Refer to this post, if you have problem installing the application

According to this link, the workaround is to clear the ClickOnce cache of application manifests before reinstalling. To clear the ClickOnce cache,

1. Open command prompt by inputting cmd in Run from Start menu.
2. Switch to the path which mage.exe is in. In my side, the path is C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin. Input "cd C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin".
3. Now input Mage.exe -cc. It will appears a notice: Application cache cleared

Encrypt Sync 4 Cloud

Background
  
If you use cloud storage for sharing or backup, it is utmost important that the files there are encrypted and only allow those you wish to share can open them. So far, I have not seen any tool that can do what I wanted, and therefore decided to write this application. Well, this changed from 15 Jan 2014, when I found out about that PKWARE "Viivo" is capable of doing similar feature, the link is http://www.viivo.com/. However do take note that, my application does not incorporate proprietary encryption which Viivo does, my application make use of OpenPGP algorithm. So pick your choice!

To protect your files from unwanted access, I have created a software that works with GnuPG (open PGP tool) to securely encrypt your files and store them into the folder that will be synced to the cloud or folder in your backup drive

If you are not familiar with GnuPG, no worries, just install the GnuPG. Use password instead of PGP key to perform the encryption.

Enjoy your life!
