How to manually uninstall a program.
I am trying to manually unistall BitDefender because it won't allow me to do it automatically and I installed the Windows Install clean up to begin with. I clicked on the BitDefender in that program and than I went to open reg edit and it gives me this error message " This program has performed an illegal operation and will be terminated. Quit all programs and than restart your computer. If the problem consistently encounters problems, click the start button, then select Help, Troubleshooting and "If you are having trouble running MS-DOS programs" and than I select the details and it tells me " The program tried to execute an invalid instruction. Fault Location- 0F10:0112 Interrupts in Service- None" Anyways I tried restarting and it didn't work and than I tried the help option but it didn't have anything on regedit so obviously my question is what happened and how can I fix it? I am a lady so sorry for the details and the idiocy. Any help would be greatly appreciated. Thank you!
This question was answered on June 9, 2005. Much of the information contained herein may have changed since posting.In order for you to manually uninstall BitDefender you will have to modify your registry Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved Use Registry Editor at your own risk
You should make a backup copy of the registry using the following steps:
1 Click Start, click Run, type scanregw, and then click OK.
2 When you receive a prompt to back up the registry, click Yes.
3 When you receive the "Backup complete" message, click OK.
NOTE: When you back up the registry, the Rb0x.cab file is created in the Windows\Sysbckup folder (where x is a number from 0 to 5) Each time you back up the registry, the oldest Rb0x.cab file is overwritten Windows Registry Checker backs up the System.dat, User.dat, System.ini, and Win.ini files, as well as registry configuration information (including user account information, protocol bindings, software program settings, and user preferences).
Follow the next steps to remove BitDefender manually:
1 Click Start, click Run, type regedit in the Open box, and then press ENTER.
2 Locate and click the following registry key:
3 After you click the Uninstall registry key, click Export Registry File on the Registry menu.
4 In the Export Registry File dialog box, click Desktop in the Save in box, type uninstall in the File name box, and then click Save.
5 Each key under Uninstall represents a program that appears in Add/Remove Programs To determine which program that each key represents, click the key, and then view the following values:
DisplayName - the value data for the DisplayName key is the name that is listed in Add/Remove Programs-and-
UninstallString - the value data for the UninstallString key is the program that is used to uninstall the program
6 After you identify the registry key that represents the program that is still in Add/Remove Programs, right-click the key, and then click Delete.
7 After you delete the key, click Start, point to Settings, and then click Control Panel.
8 In Control Panel, double-click Add/Remove Programs.
9 In Add/Remove Programs, verify that the program for which you deleted the registry key is not listed.
10 If the program list is not correct in Add/Remove Programs, you can double-click the Uninstall.reg file on your desktop to restore the original list of programs in the registry.
11 If the program list is correct in Add/Remove Programs, you can right-click the Uninstall.reg file on your desktop, and then click Delete.
