A damaged or unregistered Windows Installer service in a Windows XP operating system does not allow any program to successfully install in Windows XP. To overcome all the hazards created by damaged Windows Installer service, you will need to make a lot of changes in Windows registry. A slight wrong change made in the Windows Registry can result in complete loss of data stored on your hard drive. For complete recovery of data under such situations, you will need to restore the backup from an updated backup. But if in case, no backup is available or backup is unable to restore the data, then you will need to opt for advanced data recovery software that can recover your lost data.
Consider a practical scenario, when you attempt to install Microsoft Plus! Program on your Windows XP system, you encounter the below error message:
“The Windows Installer Service could not be accessed.
This can occur if you are running Windows in safe
mode, or if the Windows Installer is not correctly
installed. Contact your support personnel for assistance.”
Or
“The Windows Installer Service could not be accessed.”
Cause:
The above error message primarily occurs when the below conditions are true:
Windows XP is in Normal mode when you are trying to install the program.
The Windows Installer Service is unregistered or damaged.
Resolution:
For complete resolution of the above error message, you will need to take below steps:
1.You will need to log on to your system as an administrator.
2.Then you will need to click Start, and click Run.
3.Type cmd in the Open box, and then click OK.
4.Type msiexec.exe /unregister at the command prompt, and then press ENTER.
5.Next, type msiexec /regserver, and press ENTER.
6.You will need to verify that the SYSTEM account contains all control access permissions to the HKEY_CLASSES_ROOT hive in the Windows registry. Restart your system.
However, while verifying the HKEY_CLASSES_ROOT hive in the Windows registry, you might have to add Administrator accounts – which requires many changes to be made in Windows Registry. A slight wrong change in Windows Registry settings can result in making your operating system unbootable. In such situations, the best way is to re-install Windows XP. A clean reinstall of Windows XP results in complete loss of hard drive data. To recover the lost data after re-installation process, you will need to use powerful
data recovery software. These data recovery applications allow you to recover recover all the lost data by using advanced scanning methods. Such
partition recovery tools are build with highly interactive user interface that makes them easy to understand.
