Solution 1: Install Package in an Un-Encrypted Folder

Try installing the package to a folder that is not encrypted. However, if the error still persists, try other solutions listed below.

Solution 2: Enable Full System Control Permissions

Sometimes the error may occur when you don’t have system full control permissions. To enjoy full control permissions here’s what you need to do, go to my computer and right click the drive that you wish to install the Windows Installer Package to.

After that click properties and the security tab. If you can’t locate the security tab, this means your Simple File Sharing feature is turned on.

You need to turn it off to continue. For that go to my computer, tools and then click folder options. Now here press view tab and check the Simple File Sharing box to turn off.

Press OK to save changes. Now you will be able to locate the security tab.

Click on the security tab and verify the name box that contains the system user account. If the system user account is empty then insert the account name. To insert, click add, and the select users dialog box, add name and close.

Now go to the permissions section and check the box ‘Allow’ under full control. After that go to ‘Advanced’ tab and do the following: If you are XP user, select ‘Replace permission entries on all child objects with entries shown here that apply to child objects’ and then press OK to confirm.

If you are not an XP user, then follow the same instructions but select  the check box that says ‘Reset permissions on all child objects and enable propagation of inheritable permissions’ for the system account. Now click OK to confirm.

To activate changes you will have to wait for a while. Once the changes are activated, try installing the Windows Installer package again.
