Re: Steps To Restore The Missing Windows Installer Cache Files Recovery

[Nereu Theiss]

The Windows Installer Cache is used to store important files for applications that are installed by using Windows Installer. By default, this cache is located in the c:\windows\installer folder, and it should not be deleted. If the installer cache is compromised, you may not immediately see problems until you take an action such as uninstalling, repairing, or updating a product.

If application files are missing from the Windows Installer Cache, ask the vendor or support team for the application about the missing files. You must follow the procedures or steps recommended by the application vendor to restore the files. In some cases, you may have to rebuild the operating system and reinstall the application to fix the problem.

When you install a SQL Server service pack or cumulative update, you may encounter various error messages or unexpected behaviors that indicate Windows Installer Cache problems. The Windows Installer Cache, located in the c:\windows\installer folder, stores critical files for applications installed through the Windows Installer technology. If the installer cache has been compromised by deleting files, you may not immediately encounter problems until you uninstall, repair, or update SQL Server.

These problems may occur when the Windows Installer database file (.msi) or the Windows Installer patch file (.msp) is missing from the Windows Installer cache. The Windows Installer cache is located in the folder: %windir%\installer.

Repair the common shared components and features first, and then repeat the command to repair the installed instances. During the process, the setup dialog box disappears. As long as the progress window doesn't show an error, the process proceeds as expected. If the installer cache file for a specific component is missing, the repair process encounters an error.

You can use the FixMissingMSI tool to identify MSI and MSP files that are missing from the Windows Installer cache. As an extra resolution, you can point the tool to the original media location and recache the missing files.

Action needed, recreate or re-establish path to the directory: G:\x64\setup\sql_engine_core_inst_msi\then rerun this script to update installer cache and results The path on the line above must exist at the root location to resolve this problem with your msi/msp file not being found or corrupted, In some cases you may need to manually copy the missing file or manually replace the problem file overwriting it is exist: Copy "G:\x64\setup\sql_engine_core_inst_msi\sql_engine_core_inst.msi" C:\WINDOWS\Installer\19b4d2.msi Replace the existing file if prompted to do so.

This command forces the executable to extract the files to the previous missing location, and this re-creates the structure that is required to update the Windows installer cache with any missing files. The actual location will vary, and a single patch, such as a service pack, may have to be extracted to multiple locations. Each installed product includes a section that contains the following information for patches installed:

To obtain a list of all the missing Windows Installer cache files that are related to the SQL Server product components, you can download the SQL Server 2008 R2 BPA tool that is mentioned in the More information section.

Different versions of the product generate different error messages for the problem that is described. The error messages that are mentioned in the Symptoms section appear for updates starting with SQL Server 2008 SP1. For other updates, you receive error messages that may not clearly specify which patch file is missing from the Windows Installer cache and the specific update details. For these error messages, the setup log files will contain information about the missing Windows Installer cache file. Following is a sample setup log:

So why this error comes up ? The short answer to this question is that the Windows Installer Cache(Under C:\Windows\Installer) on your server is compromised. This folder is used to cache important setup files, and these files are needed during situations like patch upgrades or even for uninstalls. If this cache is compromised, then you will definitely need to work with your windows admins to understand why it was compromised.

I ran the command(As Admin) and it copied the files to the cached folder. I scrolled down the txt file to understand that there are multiple MSI files which are missing,and I had to run the copy command multiple times(I counted till 15 !).

When your computer is unable to boot to the operating system even after repeated attempts, it automatically starts SupportAssist OS Recovery. This recovery environment enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to factory defaults.

To restore your Dell computer using the SupportAssist OS Recovery Cloud option, you must create a USB recovery media using the Dell OS Recovery tool. Follow the steps below to create the USB recovery media.

The System File Checker feature or SFC is a program that can scan and resolve the issue of the missing or corrupted files on Windows 10 via replacing the files from the cache which stores the backup files for safekeeping within the OS.

Deployment Image Servicing and Management or DISM is the tool which holds the potential to bypass the System File Checker as the SFC solely relies on the replacement file held up in the cache. But, if they are also corrupted then the SFC protocol would not work. This is where the DISM steps in to service the Windows image file by downloading the required files from the Windows Update servers.

By following the above-mentioned methods, you can save your system from a messy situation via some collateral damage that is the data loss because of the restore. Rest assured the other methods would not result in any data loss as the system utilizes the cached backup replacement files from within the system to repair your PC.

If all of\nthe methods described above don't uncover the missing files, it is quite\npossible that you will have to restore them from your native Windows 11 backup.\nWindows 11 continues to support the two native Windows backup features:

The amount of time and effort required for each step goes up incrementally. Some steps involve additional work to restore the prior state of your PC more or less back to where it was prior to taking that step. Thus, the most important bit of advice I can dispense for those who must venture beyond Step 1 is this: make a complete backup of your system to provide a source for files and information that might otherwise go missing. Ignore this advice at your own risk.

If you need to restore a missing or corrupted file, return to the File History screen in Control Panel. Click the Restore personal files link. From the list of backed up folders, open the folder that contains the file you wish to recover. Click the file you need and then click the green Restore button.

Yes, there is. Data recovery software enables you to restore deleted files even after you have emptied your macOS Trash. This is because when the Trash is emptied, the files it contained still exist on your computer. They are logically inaccessible and data recovery software can repair the logical links, enabling the OS and applications to access the files again.

If you use a cloud backup service such as iCloud, Dropbox or Google Photos, you may be able to use their apps to recover deleted photos. Most services keep deleted files for 30 days. In addition to making sharing files easier, the ability to restore from the cloud is one of the main benefits offered by these services. Specific steps will necessarily be based on the platform you use.

The Mac equivalent of the Recycle Bin is the Trash Can. In both cases, files are temporarily stored in these special folders from where they can be restored quickly with a few clicks. Once the Trash or Windows Recycle Bin have been emptied, you need to use a backup or data recovery software to restore your data.
