Error 1001 in Windows: Exception occurred while initializing the installation.

During installation of the native install on a Windows platform the error is thrown when the install is at the "removing backup files" point.

Error 1001: Exception occurred while initializing the installation.

System.Argument Exception: String cannot have a zero length..

Acknowledging the error then removes the application.

The error is caused by files left over from a previous, other client installation. These files are located in

C:\Users\<THEUSER>\AppData\Local\Temp\ NOTE: AppData is a hidden folder

Three files can be present. RWSCleanup.dll, RWSCleanup.InstallState and RWSCleanup.txt.

Delete all three and then run the install again.

Deleting the files will not impact existing installations.
