When you access a file on a SIS managed volume, you receive:
Access is Denied.
When you right-click the file and press Properties, the Security tab is missing, only the General tab is available.
This behavior will occur if the Read-Only attribute is set for a file in the SIS Common Store folder.
To fix this problem:
1. Open a CMD prompt.
2. Switch to (CD) the SIS Common Store folder.
3. Type attrib -r *.* and press Enter.
