  Hi guys,

  I have a corrupted copy of Microsoft SQL Server installed on my computer which I intend to uninstall.

  When I try running uninstallation from Add/Remove programs, I get an error stating uninst.isu file not found and uninstallation cannot be completed

  I thought well let me just run the installation again, overwrite this corrupted installation and that would hopefully fix the problem.  However running the installation again; new copy of SQL server is installed. I can see 2 copies of SQL Server in Add/Remove programs.

  Please help!! What should I do to uninstall this corrupted copy and do a fresh installation.

  Hi Newbie!

  I hope you got your problem resolved from your post from 2004...

  Do you remember how you got the SQL Server completed uninstalled? I am running into the same problem. I have two instances of SQL Server installed now and cannot uninstall them because it cannot locate the uninst.isu file.

  Thanks

  Personally, I would feel rather uneasy about it. I would reinstall OS, of course if it was possible.

  To late, I already did what the microsoft article recommended. Scary. I have installed developer edition and all is well. It's only a personal laptop, not so much worry. Lesson learned! Keep the cd's handy!

   

  Thanks

  I had the same problem tonight, when I try to uninstall SQL 2000 Server, it didn't find the uninstall file, so what I try is reinstall SQL from de CD with setup.bat but I select modify and add one option. Then after the installation I reboot and start the uninstall from the add and remove program and SQL was remove without any problem.

  Hope this help.

  Bye

  Actually, let me more clear. The uninstall "succeeds" after adding a single option, but I think that uninstallation only removes the registry settings. In any event. That's a big help, of course.

  I also tried with setup CD to create 'uninst.isu" file using Upgrade option.

  This does not worked for me.

  Manually uninstall ed as per the MS article.
