When trying to install some programs such as Microsoft Office, the users will annoyingly get a Windows Installer error message saying that “The Windows Installer Service could not be accessed”. Thus, the install process just hangs or stops responding. Typically, such a Windows Installer error could be caused when a file relating to the Windows Installer has been missing or damaged. After talking about the application error 0Xc00007b in luanching a app, I will show you some steps to fix the annoying Installer error.
When getting a Windows Installer error message in installing a program, directly follow the steps here to reinstall the Windows Installer on your computer:
*Click Start, go to Run, type cmd in the Open text box, and then click OK.
*Type cd %windir%\system32, and then press ENTER to continue.
*Type attrib -r -s -h dllcache, and then press ENTER to go.
*Type ren msi.dll msi.old, and then press ENTER.
*Type ren msiexec.exe msiexec.old, and then press ENTER.
*Type ren msihnd.dll msihnd.old, and then press ENTER.
*Type exit, and then press ENTER.

*Click Start, click Turn off computer or Shut Down to shut down the computer.
*Select the Restart option, and then click OK, or click Restart.
*Log on to the computer again and then download & install the latest version of the Windows Installer.
Sometimes, you might get the Windows Installer error message when your hard drive has a bad sector, which will stop the system to read or write anything from/to the hard disk. So, the second thing you should do is to check & fix all hard disk errors and bad sectors immediately. You can use Windows Disk Manager tool to check & fix all file system errors and bad sectors on your hard disk. To do this, you can easily perform the below steps:
* Right click on the hard drive and click Properties
* Click Tools tab and click “Check Now” under Error-checking.
* In the dialog box select the “Automatically fix file system errors” or/and “Scan for and attempt recovery of bad sectors” check box to automatically fix all file system errors and bad sectors.
Thirdly, to prevent further Windows Installer error messages, it is highly recommended that you should regularly scan for viruses and remove PC threats. If you have never detected a virus for your PC, you must have been worried about losing your valuable office documents, personal images, songs etc. In fact, your computer will start showing common symptoms of a virus infection like freezing at times, shutting down itself, and a non-responding web browser among other things if the computer was infected. One some needed files were mis-deleted by the viruses; you will get a Windows Installer error message when trying to install a specific program. So, easily download a freeware antivirus antispyware program from the Internet and remove all PC infections immediately.
Last but not least, check and fix computer registry errors. The registry is where all system files, settings and programs are stored. No matter when you install a program to the computer, it will automatically add some corresponding entries to this database to ensure its proper running. Hence, this database will take up a large space and memory. However, it is very easy for this database to get corrupted or full with some unknown errors. When the registry develops errors the computer will sooner or later generate some unexpected errors just like the Windows Installer error in installing an application. Besides, wrongly installed or incompatible programs in the computer can also cause errors to occur. Directly download and run a registry error fixer to completely scan and remove all PC registry errors from the PC. Then I believe you can enjoy an error-clean system all the time without issue.
Well, it is necessary for us to rely on a variety of programs either for our work or study in our daily life. Thus, a sudden Windows Installer error message can be very annoying and should be fixed timely.
