Recently, I saw a netizen asking for help, saying that I had a strange problem. When installing or uninstalling some applications, the system actually prompts Windows Installer error, "Cannot access Windows Installer service", can not complete the corresponding operation. Until the first 2 days Xiaobian gave my love machine upgrade Office 2003 also encountered the same problem, I finally made up my mind to solve this ill! Search on the network to get the following solution:
If your system is WinXP When installing Office 2003, "There is no access to the Windows Installer service. It may be that you are running Windows or Window Installer in a secure mode. The error is not correct." (In fact, all MSI format programs installed using the Windows Installer service cannot. Normal installation); in the "Services" view the status of the "Windows Installer" service, generally disabled, when you try to enable this service, you will find that this service has been disabled by the system, or the Windows Installer service has been Marked as deleted; when you try to reinstall the Windows Installer service, the system prompts "The specified service already exists" ”—— then this article is what you want.
Workaround (passed on WinXP/Win2000):
First write the following content in Notepad and save it as installer.reg format file, double-click to import the file into the registry;
Run“CMD” command At the prompt, type “msiexec /regserver” and press Enter;
No need to reboot, immediately mess up!
