Hi folks,
When installing the SharePoint 2013 Preview Prerequisites you may get the error message "Appfabric installation failed because installer MSI returned with error code:1603". In my case it happened because I had uninstalled Appfabric and tried to install it again.
Solution
In order to eliminate this error, the Powershell path must be mapped to the Environment Variable PsModulesPath.
Add the following path:
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
Then you may proceed with the installation of the SharePoint 2013 Preview Prerequisites.
I hope it helps.
Cheers,
Marcel Medina
