Hi there,
I found that many person have difficulty to remove or uninstalling SQL Server 2008 R2 from instruction that already gave by MS.
You have to delete the unnecessary file or folder which have related or contain SQL Server 2008 keyword. but the second problem show up when you want to install it again after you remove the first one.
does anyone can help me and other people who want to remove or uninstalling SQL Server 2008 R2 and then Installing again without having errors or difficulty to doing that ?
