When I Open any app on my Nokia 2690 it Shows "supporting file nothing to show" and app is either working or getting installed e.g. Calculator, opera-mini etc.

The inbuilt calculator should be in the organizer. It's kind of strange that the calculator is missing because you can't delete or move this application. Try a reset by typing *#7780# and the password is 12345. The other option is firmware update using a PC Suite.

download calculator jar file connct yo phone and make sure its detected on the pc suite.then just double click on the file and walla: its installed to the phone

Flashing of phone is the only solution.It occurs when phone is infected by virus which is influenced from memory card or the file we got it via bluetooth.So contact mobile repairing shop or follow the procedure I've given below.

First download and install Pheonix from this link. Nokia Phoenix Service Software 2011 - Download secondly Download flash file from this link 2690 Flash File and install it to C / program files/pheonix.. after finished this installation open pheonix . Inside the interface at the> top left <there you see "File" click there and choose "open file" and then select the approprait Product type i.e "which is written on the back panel inside the battery of every Nokia(Type RM-000).After doing this again at the left top count from "File"1..2..3..the 4th one is "Flashing" press there, when you click there you'll see three sub-menus, just select the "Firmware Update" again you'll see another interface. Look at the product code there should be blank and put your "mouse tool" at the straight end from the "Product Code" there is a Button and choose the code which is written in the back side of your phone. e.g CODE:0000000.if the same code does not found just take one which is higher. After this you can see "Dead phone USB flashing" click that box. Now this is the last stage... Connect your phone with the USB to your PC and let the driver install ...wait for a moment.(If your phone working).Lastly after just finished (In case your phone is Dead, unable to switch on in normal mode start from here) Connect the phone to pc without powering...insert good battery and Click the "Referbish" button after this, a message will prompt you "press power botton" etc. insert charger or press it and wait until the phone will Restart automatically in normal mode 10-15 minutes.

The calculator function on a nokia phone cannot be missing from the device unless the firmware on the unit is bad. It is either the calculator has been moved to a different location or you have not been able to locate it. Check the organiser pane on the phone and the calculator is supposed to be in there.
Hope this solution has been helpful?

first check that the downloaded file is a executable jar file.If it is,then try to install this application by nokia pc suite
