Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Sometimes the easiest way to fix these issues is to run the VDA Cleanup Utility.

If this does not work, follow the steps below : 
1-uninstall Workspace and  VDA software on the server
2-rename (with .old) the folder listed below :

C:\Program Files\Citrix
C:\Program Files\Common Files\Citrix
C:\Program Files (x86)\Citrix
C:\ProgramData\Citrix
C:\Users\<MyUserID>\AppData\Local\Citrix

And the following registry entries :

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Citrix

After that, the installation of the VDA is now in success.
