"The data is invalid" and "Signature not found".

Hi,

My ThinApp gives error as "The data is invalid" and "Signature not found" when user click on shortcut to launch the ThinApp exe. ThinApp exe is located at server and shorcut is available at client maschine. This error does not happen on every machine only on some machines.

Please any one give me solution to rectify it ASAP.

Thanks

Arjun
