package - Caterpillar GERP 4.05 when deployed in test environment, it installs fine in both 32 and 64 bit win7 systems in system context.
when deployed to client environment - program to run in system context - installs fine in 32 bit win7 machines but fails in 64 bit win7 machines however manual installation works fine.
till now in client environment all the packages installed fine in 64 bit machines, this is the first package with unique issue.
installation via user context for 64 bit win7 device doesn't work.
how to troubleshoot and fix this.
