12.8 Troubleshooting  
Below is a troubleshooting guide that can help you resolve any problems that might occur. 
 
Installation says you do not have write 
permissions in this folder  
You are probably not permitted to change the folder in which you are 
trying to install PC Sync. Try installing it in another location.  
Phone displays “HTTP error, HTTP 
request failed“  
Please make sure PC Sync is started in the PC.  
Please check if the same port is set on the phone and on the PC  
Please check you correctly entered PC address.  
Please check your firewall settings. The port may be closed by the 
firewall. Try to change the port.  
PC Sync displays “Unable to listen to 
the port“  
Please make sure no other applications are using this port.  
Please make sure the firewall allows listening to this port. Try to 
change the port. 
PC Sync displays “Selected folder has 
been deleted“ or “Cannot open 
Outlook profile“  
The profile or the folder that Contact-Sync is configured to 
synchronize with has been deleted. Select another profile or folder in 
settings. 
PC Sync displays “Outlook is not 
installed“  
Contact-Sync could not find a supported version of Outlook on the PC. 
Install Outlook.  
PC Sync displays “Error 
communicating with Outlook“  
Contact-Sync could not communicate with Outlook. This might be 
because Outlook has been installed but not yet set up properly or is 
malfunctioning. Starting Outlook itself may provide information on 
what is wrong. 
Contact-Sync displays 
“Synchronization has failed. An error 
during data exchange with computer 
has occured“  
Please make sure PC Sync is started in the PC.  
Please restart Contact-Sync. 
Please check if Contact-Sync has run when Windows has started 
(enable the startup option in configuration of the application). 
Nothing happens when I press the 
Synchronization button on the phone 
(no Synchronization dialog appears in 
Contact-Sync). An error message 
appears stating “Synchronization has 
failed“.  
Most likely there is a mismatch in protocols: the phone uses HTTPS and 
Contact-Sync uses HTTP or vice versa. Try to check or uncheck the 
“Use secured connection“ Ý checkbox and restart synchronization. Ask 
your system administrator which protocol your phone uses.
