Reinstall Troubleshooting

Reader Question:
“Hi Wally, I am having problems with Reinstall and wondering how to fix it?”    - Mark M., USA

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer:

Overview of Reinstall

It is sometimes necessary to reinstall an application. There are numerous reasons this may be required.

Sometimes an application will become unstable because of a virus or malware infection. When the antivirus software removes the infection, it sometimes finds it necessary to remove certain critical files that run an application because the files cannot be repaired.

Sometimes a user prefers the way a program performed before an update or patch was applied. Removing the update or patch is often not possible, so uninstalling the program in order to reinstall it without getting the update is necessary. Some applications, like Yahoo Messenger, will require that a new version be installed rather than applying a patch or update.

In some cases, the patch or update may cause the program to become unstable and it is necessary to reinstall the program in order to use it again. Many applications will require the program be uninstalled before it can be reinstalled on the computer.

Other programs will allow reinstallation over the top of the existing installation. In these cases, the reinstallation process will overwrite the existing program files.

What Problems are Associated with Reinstall?

One of the most common errors experienced when reinstalling any application is, “1603: Fatal Error During Installation.” The most common reason is a critical file is locked and cannot be overwritten. Even if the program was uninstalled first, there are often several files that remain behind.

Registry files, for instance, are rarely removed during the uninstall process. Viruses can also lock certain files they have infected to prevent them from being removed or changed.

Another common reason for this error is that the temporary folders are already full. The installer program first moves all the necessary files to a temporary folder and then installs the program. If there is not enough room in the temporary folders, the user will receive a 1603 error and the installation will be cancelled.

Another common error during reinstallation is, “MSI Error 1935.” This error is often caused by a program conflict. Sometimes the conflict is with the antivirus or firewall software, but most of the time it is with one or more of the background services. These services start and run without the user being aware of them. Many of these services are necessary make other programs function correctly. Temporarily disabling the service or program creating the conflict will allow the reinstallation to proceed.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
