I have NAV 2009 SP1 installed in my Laptop.
Now I am trying to install NAV 2009 R2, for this I have done following steps..
1) Uninstalled from Control Panel and Setup.exe
2) Deleted Microsoft Dynamics NAV Folder from C:\Program Files (x86)
3) Restarted Laptop
4) Ran setup.exe from R2 DVD folder
Now the error message is attached
and Microsoft Dynamics Server service is not installed in Services..
If I try to install Service manually it is displaying
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.
If I look at Add/Remove Programs on the Control Panel, I found nothing related to NAV 2009 SP1..
FYI:I am the administrator of Laptop.
What am I missing? :-k
