Efforts to use, repair, and uninstall Blackberry desktop software failed. Help?

Question

I upgraded from XP to Windows 7, and had to reinstall the Blackberry Desktop software.  I'm looking for help to get it working.  I've installed version 6.0. i'm on Curve 8330 (Verizon).  Below describes mt efforts:
When I run the desktop software, I click "organizer', and then I connect the BB and wait unti the bottom right of the BB desktop software says "connecting...' then "sync".  i then click the "configure settings..." and get a pop-up window titled "blackberry data synchronization" with message "operation in progress.  please wait".  The pop-up window self-disappears. It reappears every time I click the "configure settings..." button.  However, this has run for hours.  The software appears to be stuck in some sort of infinite loop.
So, I tried to repair the software as follows: Start - Control panel - programs and features - blackberry desktop software 6.0 - Next - Next (Repair is checked) - Install.   I get a window titled "blackverry desktop software 6.0" that reads "The feature you are trying to use is on a netword resource that is unavailable.  Click OK to try again, or enter an alternate parth to a folder containint the installation package 'blackverry desktop software.msi' in teh box below.  Use source: C:\Users\Jim\AppData\Local\Temp\WZSE0.TMP\
.  I clock ok and try agin and get the message "the path 'c:\users\myname\appdata\local\temp\wzse0.tmp\blackberry desktop software.msi' cannot be found.  verify that you have access to this location and try agin, or try to find the installation package 'blackberry desktop software.msi' in a folder from which you can install the product blackberry desktop software 6.0'  I am unable to find this file on my computer, but "windows search" has been less than 100% successful for me in Windows 7.  So, I clicked "cancel", and get the following message: "error 1706. No valid source could be found for product blackberry desktop software 6.0.  the windows installer cannot continue. So. I click "finish".
So, I try to uninstall the software altogether as followstart - Control panel - programs and features - blackberry desktop software 6.0 - Next - Next (REMOVE is checked) - Next ("Remove all user settings for Blackberry desktop software" is checked.) - Remove.  I then get the following message: "error 1316.  A network error occurred while attempting to read from the file c:\windows\installer\blackberry desktop software.msi".  When I click "ok" to this window - I see "rolling back action" status bar. I then click "finish".
So,my efforts to use the software, repair the software, and uninstall the software have failed.  Any advice?
I see no "blackberry desktop software.msi" in the c:\windows\installer\ folder.  I am able to view hidden files in Windows Explorer (Tools  Folder options... - View tab - "show hidden files, folders, and driver" is selected".
I'll restart my windows search index tonight.

Thank you Viciousferret,
I re-downloaded the the 600_b047_multilanguage.exe to my PC using thelink you provided.  I then ran it.  I then did the following:
selected "NExt",
then "REMOVE" (the options were "repair" and "remove", not "modify" or "uninstall"), then NEXT,
then checked "remove all user settings for blackberry desktop software".  then NEXT
then the REMOVE button
then FINISH
So, it appears the uninstall was successful. 
The next step of your suggestion was to: "Then proceed with the clean uninstall by performing all the steps: www.blackberry.com/btsc/KB02206"  This link provides 5 tasks. 
1) The first task includes instructions to ": Uninstall BlackBerry Desktop Software".  Should I skip this step because I already did it above?  If not, would you please provide the instructions for Windows 7?  Only instructions for other operating systems are shown here.
2) The second task is to "remove computer registry entries".  The fifth step gives instructions for XP, Vista and 7 64-bit.  i use Windows 7 (32-bit).  Are you able to provide the instructions for Windows 7?  Also, the instructions to back up the registry are: "select My Computer (or Computer in Windows Vista) at the top of the folder structure, click File, and choose Export to export the file to your preferred location.'.  When i select start then Computer and then click File (after verifying the "Computer" is highlighted in theWindows Explorer window, I am not presetned with an opportunity to click "Export'.  My options are 'add a network location", 'create shortcut (greyed out), "delete", "rename", "properties" and "close".  Are you able to provide additional guidance as to how i am failing see "export" when i seemingly follow these instructions?
3) Step 3 gives instructions for deletig folders from teh computer.  It also lacks instructions for Windows 7.  Are you able to provide them?
4) Step 4 provides a link to follow.  that link also lacks instructions for Windows 7 (32-bit).  Would you be able to provide instructions for Windows 7 (32-bit) users?
