Error while installing manage engine desktop central 8

Error while installing manage engine desktop central 8

Hi..

I am trying to install manage engine desktop central 8 on my work PC. But after accepting the license agreement and continuing with the default port it gives me an error as follows,

Component :  sourceComponent
file group :     sourceFiles
file:    cannot create a file when that file already exists
this error comes when the setup is at 2% and the path shown is c:\...\setup.inx

after which the setup stops.
any solution ???
