. Q: Some softwares always prompt to install the software before installation, and then prompt to restart the latest system download and then install, but after the restart, the problem remains. Excuse me, how to solve such a problem?
A: This is because the software was installed before, and then the registry related registration items are not cleaned up when uninstalling, so every time the software is installed, the installer detects the registry. There is a corresponding option, and you may be prompted to restart the system. The solution is to manually delete the information of the software that exists in the registry. The specific steps are as follows: run regedit, open “ Registry Editor, click on the menu bar, click “ Edit & Rarr; Find & rdquo; Open & ldquo; Find & rdquo; window, select “ item, value in this window , data ” three options, then enter the software name in the "find the target", click the "find" button, if you find the relevant item, delete it directly, and then press the "F3" key to continue searching Until the entire registry search is completed, and finally restart the system, the software can be successfully installed.
Common Software Installation Failures Quick Troubleshooting
1.InstallShield
For InstallShield 6.X installation program, if the installation error includes: does not support this interface, RPC error, Ikernel error and other error messages, you can try the following method.
(1) Use the “Task Manager” to check whether the Ikernel.exe process exists. If it exists, and confirm that no installer is running at this time, you can end the process and then install it;
(2) Delete the Installshield directory, such as deleting the directory C:\\Program Files\\Common Files\\InstallShield\\Engine and C:\\Program Files\\Common Files\\InstallShield before installing;
(3) The following registry keys cannot be read (account Low level or registry permission setting error):
[HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\CLSID], [HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\Interface], [HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\TypeLib], after this problem occurs, Use Regedt32.exe to change the account level and change to administrator privileges.
(4) If you still can't solve it, you need to log in to the Installshield website to search for the answer.
For example, an error occurred in the installation of "Error -1608: Unable to Create InstallDriver Instance", and then enter 1608 in the Search Consumer Central to find a solution to the problem.
2.Wise Install System
If it is an installer made by Wise Install System, you can also go to Wise website to find the answer, similar to InstallShield, enter keywords in All of these words, then Select Problems in the Article Type, check the operating system, and select Products as the Wise Installation System.
3.Inno Setup
Because the Inno Setup script file is very simple, there is no detailed database on the website. If there is a problem, look for it.
4.MSI format
Because the MSI installer uses the system service Windows Installer, once the service is faulty, it will lead to various installation errors. For example, the 1603 or 1601 error encountered when installing MSN Messenger 6.0 is generally caused by Windows Installer. If the Windows Installer service is running, you can first try to stop the Windows Installer service by typing "msiexec /unregserver" (without quotes) in “start →run", and then use “msiexec.exe /regserver”( No quotes) Enable the service. If all programs installed using Windows Installer are not installed properly, it will also appear that you cannot access the Windows installer service. Maybe you are running Windows in safe mode, or the Windows Installer is not installed correctly. Please contact your support staff for tips on getting help. Usually the Windows Installer service has been deactivated in this case, and when the service is enabled again, it will prompt "The specified service has been marked as deleted". And when trying to reinstall Windows Installer, the error "The specified service already exists" appears. This situation is caused by some software production problems that cause Windows Installer to not work properly. The following method can be used.
1. Delete the [HKEY_LOCAL_MACHINE\\SYSTEM\\ CurrentControlSet\\Services\\MSIServer] item in the registry, then run instmsiw.exe, if you can not continue the second step.
2. Right click on the file and select "Install" to delete some MSI dlls. Note that Windows may warn that some system files have been modified to insert the installation CD and ignore them.
3. Restart the computer, press F8, enter "Safe Mode with Command Line", execute the following command:
regsvr32 /u %windir%\\msi.dll
del %windir%\\msi .dll
4. Restart xp system download, run instmsiw.exe, install Windows Installer2.0.
If only a program created with Windows Installer cannot be installed, you can use Microsoft's Windows Installer CleanUp Utility to clear the system cache installation files, or to the Installer directory under the Windows 7 folder (the directory is hidden) Directory), delete the MSI file and reload it.
