I too had seen an old thread with the mention of firewall problems,
My problem persists even after disabling firewall (and still persists after re-enabling firewall)
I do however have a 'functional' if less than perfect resolution I found elsewhere that has resolved my problem. I shall include some details below for you so that you may be able to help others in future.
Please note: The resolution I have used is not useful for those that are not comfortable editing with regedit.
Furthermore, the resolution I propose is to disable Windows UAC and this renders the computer more vulnerable to potentially malicious software.
While I'm personally happy to go through this process others might not.
I shall state however that I do intend to restart UAC once I have actually found a proper and fitting solution to my problem.
Manually disabling UAC from within Windows:
- Press WINDOWS KEY + R
- Type regedit
- Click OK
- Click Yes if prompted
- Go up to the top to File and then down to Export and save a backup somewhere you will remember
- In the left pane, browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- In the right pane, double-click EnableLUA
- Change Value Data to 0
- Click OK
- Close the Registry Editor
- Restart the computer
Again I thank you, Andre for your effort in attempting to help.
