QUESTION:
How can I make sure I have a list of all DLLs necessary to run my report at a deployment machine? The report works on my development machine, but when testing on a deployment machine it did not run...

ANSWER:
Use the attached Modules.exe - provided by Crystal Decisions - to do the following:

1) Run Modules on the machine where the report works
2) While Modules is running in the background, call the report.
3) Select File | New List | Memory Modules in order to generate a list of all the DLLs and components accessed and available on that machines
4) Select File | Save As to save this list to a "log" file
5) Run the same thing on on the machine where the report doesn't work
6) Within Modules, open both log files generated
7) Click on the tree of the log from the working machine, and highlight "For All Dlls" under "All"
8) Select the option "Module | Differences"
9) On the righ panel, highlight "For All Dlls" from the other log file (generated for the machine where the report does not work) - make sure you have selected the appropriate "Attributes to compare" checkboxes
10) Press OK to compare the DLL's installed on both machines using their respective lists
11) All the differences between the two log files will be displayed
12) Ensure that the complete list of DLLs is available on both machines


Notes:
- Search and download the latest version of Modules from Crystal Decisions website
- Possible error that you can get for a missing DLL includes "Not enough memory for operation"
- To know where a DLL is being loaded from, just double-click on the DLL name from the "By DLL" tree

Important!
From the Crystal Reports Designer, the option Help | About Crystal Reports | More Info lists all the DLLs used by the report and the path where they are being loaded from.
