when I tried to install our unmanaged package I recived below error

"Your requested install failed. Please try this again.

None of the data or setup information in your salesforce.com organization should have been affected by this error.

If this error persists, contact salesforce.com Support through your normal channels and reference number: 1254580032-60446 (356011732)"
I have tried the installation several times and continued to get the error.

Any solutions?
