2908 installer error - Dave

Hi,

We have been having a problem with some users getting a 2908 installer error
when they install our product.  This started happening after we added
Crystal Reports merge modules to the installer and it starting taking an
extremely long time for the installer to come up. We have since removed CR
into its own installer, but we are still seeing some users who get this
error.  I am wondering what could be causing this error. We know of two
scenarios:  1. The user clicks on the installer multiple times and as a
consequence has multiple installs going unintentionally  (due to the burden
of having 70 mega of Crystal Reports Merge Modules in the installer causing
it to launch slowly).  2. The user had the program being installed up and
running and ran the installer.  Can anyone tell me what else produce this
error, and what can be done to repair after the error occurs? We have been
reinstalling windows on computers affected with this error. Any advice on
cause and friendlier recovery would be appreciated.

Thanks,
Dave
