I would suggest you remove all OS and desktop manager from PC, delete remaining files from your shared folder of research in motion. Do a PC reboot.

Reinstall DM and the OS required and follow this for updating...

ELITE1's OS UPGRADE GUIDE
(updated 2012-09-01)

1. (Optional) Uninstall any previous OS from PC.
2. Download OS to PC. Use Internet Explorer, not Firefox or Chrome. (For leaked versions, browser is irrelevant.)
   *If 100% certain you previously used FF or Chrome on same PC to DL an OS successfully, feel free to use FF or Chrome again.
3. Following successful DL, run OS file to install OS on PC.
4. On BB, go to BBM Options, scroll down to Backup section. Ensure Remote Backup is enabled AND also conduct a Local Backup to media card.
5. Go through any 3rd party apps with option to save settings to media card. Conduct Backup to media card within each of these apps. (Examples: Bellshare apps like BerryBuzz & BerryWeather; QuickLaunch; Shao's apps like Wallpaper Changer & SixTools; etc).
6. Connect BB to PC. Open DM and backup device. Close DM.
7. (Optional) Use desktop app like BBSAK or BBMCP to backup 3rd party apps.
8. On PC, delete Vendor file located here:
   64-bit: Computer/C:/Program Files (x86)/Common Files/Research In Motion/AppLoader
   32-bit: Computer/C:/Program Files/Common Files/Research In Motion/AppLoader
9. (Optional/Recommended) Run BBH Tool (formerly Shrink-A-OS) or BB Boss v2.2 (not as updated as BBHT).
10. In same AppLoader file where you deleted Vendor, double-click Loader to load OS to BB. Follow onscreen instructions.
11. After loading OS, perform several physical battery pulls over first 1-2 days for OS to "settle in." Perform first batt pull very soon after OS is loaded.

**TROUBLESHOOTING**
How to Fix OS not Appearing as Available
There are 2 common reasons:

A. HIDDEN VENDOR FILE
Consider trying this new desktop app to remove Vendor from several common locations:

If manually deleting Vendor, always hold down SHIFT and press DELETE to permanently delete.
Check here first:
64-bit: Computer\C:\Users\{USER NAME}\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
32-bit: Computer\C:\Documents and Settings\{USER NAME}\Application Data\Research In Motion\BlackBerry\Loader XML
If Loader still doesn't make new OS available, search PC for "Vendor".

If Vendor is not found anywhere, see below to delete contents of AppLoader folder. (Folder where you found Loader & Vendor.)

B. APPLOADER FOLDER ITEMS

1. Uninstall the OS: Control Panel\Programs and Features, highlight this BlackBerry Device Software, click Uninstall at top.
2. Delete AppLoader folder contents: Highlight any item, CTRL+A to select all, SHIFT+DELETE to permanently delete.
   64-bit: Computer/C:/Program Files (x86)/Common Files/Research In Motion/AppLoader
   32-bit: Computer/C:/Program Files/Common Files/Research In Motion/AppLoader
3. Restart PC.
4. Re-install OS on PC: Go to your browser's downloads section, double-click OS to start InstallShield Wizard.
5. Delete Vendor: Return to AppLoader folder, highlight Vendor, SHIFT+DELETE.
6. Load OS to BB: Attach BB to PC, double-click Loader (in AppLoader folder, where you deleted Vendor).

PS I've posted this before in other threads, but there always seems to be some people that appreciate a step-by-step each time.
