Installation of Crystal Reports does not really have any issues on a 64 Bit machine.
But once installation is over and you launch the Crystal Reports, you would be surprised to see Crystal Reports Application crashing.
The reasons are two:
1. Crystal Reports Redistribution x64 must be installed on 64 Bit machines.
2. DEP (Data Execution Prevention) on that machine must either be set to “Essential Programs and Services” alone, or create an Exception for Crystal Reports EXE. This will ensure that OS does not validate Crystal Reports and throw an exception error, which leads to crashing.
