Calendar won't open - crashes desktop

Question

Treo 650/Win XP
Installed desktop 6.2 and now it crashes every time I try to open calendar.
(Foolishly!) Tried to install previous version 4.1.4e and now there are 2 icons in Desktop for every function. One set work and seem to be the 4.1.4e ones, the other set partly work (Tasks, memos) but addresses contains nothing (although the other icon does!) and date still crashes desktop.
I suspect and fear the answer is uninstall/re-install desktop - but does anyone have any hints that avoid this, or if not, how to do it safely?
Thanks

Answer 1

At this point, you will need to do a "clean" uninstall and re-install of Palm desktop.
Do you have your current data on the Treo or in Palm desktop?
If you have the data in Palm desktop, export the data, uninstall Palm desktop, re-install Palm desktop and import the data.
Here is a procedure for exporting the data for backup purposes.
The best way to preserve your data is to export the data in each category in Palm Desktop to a seperate folder on your PC.
Create a new folder on your PC somewhere that is convenient. Name it something like Palm Desktop Data. Click on the link below and follow the instructions on that page for the export procedure.
http://www.palm.com/cgi-bin/cso_kbURL.cgi?ID=28734
Make sure you select all for the range in the export window.
With the data saved in the folder you created, make a copy of that folder and save to a flash drive, cd-rw or external hard drive.
Anytime you make a change in Palm Desktop, export the data that was changed to that folder and save again to the external media.
With this process you can always import the data back into Palm Desktop anytime you have a problem with the data in Palm Desktop or if your computer/hard drive/device crashes.
Here are the instructions for the "clean" uninstall.
You should first make a copy of your data to have just in case something
happens. You can find your data files by going to C:\Program Files\Palm or
Palm One. Highlight your Palm Desktop username and right click and copy.
Then go to your PC desktop, right click on a blank spot and select paste.
Now you want to uninstall Palm Desktop and remove everything that has to do
with Palm Desktop from your computer. Like the above folder, delete the Palm folder. Once this is done, you will need to delete some registry keys
from your PC Operating System registry.
Word of warning, going here and deleting the wrong thing can cause your PC
to not start up, crashing and deletion of programs and data. If you feel
you are unsure of yourself, see if you have a friend that can help you or a
PC technician that you can pay to help you. This will show them everything
they need to delete. To retain your current Registry settings, we need to do a backup of the Registry.
On the PC, go to start and run type "regedit" without quotes
Highlight MY COMPUTER, go to File --> export. Should pop up with a Save As
box. Current location is fine should be in My Documents or you can change to a location you will remember. In the file name box, type "Regbackup[todaysdate]" i.e. Regbackup07072008. Next, the hard part.
The easiest way to make sure your working with the correct key, highlight the key i.e. palm quick install, and press delete on your keyboard. It will ask you, are
you sure. Say yes. Do the same thing for all keys below.
If you make a mistake, stop what you are doing. And call a PC technician.
BUT do not turn off your computer.
The reg keys are as follows (Note: some of theses reg keys will not be here
but if they are delete them)
* HKEY_CURRENT_USER\Software\U.S. Robotics\Palm Quick Install
* HKEY_CURRENT_USER\Software\U.S. Robotics\PalmOne File Transfer
* HKEY_CURRENT_USER\Software\U.S. Robotics\Pilot Desktop
* HKEY_CURRENT_USER\Software\Palm
* HKEY_CURRENT_USER\Software\Palm, Inc.
* HKEY_CURRENT_USER\Software\PalmDesktopAutorun
* HKEY_CURRENT_USER\Software\palmOne
* HKEY_CURRENT_USER\Software\PalmSource
* HKEY_LOCAL_MACHINE\Software\PalmSource or anything else that says palm
Next reboot your computer
Then reinstall your Palm desktop from the CD and do a hotsync. If it asks
you for a username and you synced your device before, put in 'test" if you
did not sync before you create a hotsync name.
For reference purposes, click on the following link for the support page for your device on the kb.palm.com webpage.
