Unable to uninstall the older version of Cummunity Edition

I am trying to uninstall teh older version of community edition, inorder to install the latest version. But I get an error while uninstalling the older version. The error says:

‘The specified accoutn already exists.’ and the uninstallation stops.
Any solution for this?

Thanks and Regards,

Dear User,

“The specified account already exists”. This is not a bug within AssistEdge installer but in .msi installers in general, where certain registry keys can become corrupted during an install or uninstall. To rectify this you may need to run the fix utility provided by microsoft from link given below-

Thanks for the response Amit. Will check this.
