Error:

Error 1406: Could not write value compatibility flags to key “\Software\Microsoft\Internet Explorer\ActiveX Compatiblity\”.Verify that you have sufficient access to that key, or contact your support personnel.

Error Message:

Causes:

1. The logged on user may not be an Administrator.
2. The user has insufficient permissions to edit or modify the particular registry.
3. The user who is installing the program does not have sufficient permissions to modify sections of the registry that is required to perform the action. The permission for the “everyone” group of the registry subkey noted in the error message is not set to Full Control.
4. There is a third-party application on the system that is denying the required access to the registry subkey. In most cases, this behavior is caused by “Antivirus“.
5. The nonadministrative user accounts on the computer do not have permission to modify specific registry.

Solution 1:

• Click Start > Run > type regedit
• Navigate to the path shown in error message
• Right click > Permissions > Select “Everyone” & “SYSTEM” account
• Give Full control permissions > Click Apply.

Solution 2:

Right click the setup and click “Run as Administrator”.

Solution 3:

Pause or Disable the antivirus and try the installation.

Solution 4:

Verify the Registry Permissions:

1. Click Start, Run > type Regedit and then press Enter.
2. Select HKEY_CLASSES_ROOT, on the Edit menu, click Permissions.
3. Verify that the SYSTEM account has been added and that it has Full control. If it does not, add the SYSTEM account with Full control.
4. Please use the same method to give Full control permission to the following registry keys:                                                                                                     HKEY_CURRENT_USER                                                              HKEY_LOCAL_MACHINE

Solution 5:

Log off current user and login as administrator. Try the installation again.
