I have uins000.exe in my Uniblue/Speed Up My Pc, that I downloaded as a trial offer. I then downloaded a free registry cleaner. Now I get unins000 error messages and cannot uninstall Speed Up My PC. From researching I have found this file is used by more than 1 software. All I want is a copy of it to put in the correct folder. I do not know if it is a generic exe or if it is tied to a certain folder. I just cant seem to find the answers.

If you delete a unins000.exe or unins000.dat file you maybe can't uninstall a program.
essential file to uninstall software installed with inno setup. This file should be in the program install dir. If you find it in other locations investigate it.

Best practices for resolving unins000 issues

A clean and tidy computer is the key requirement for avoiding problems with unins000. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the unins000.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
