the following errors were noticed

Answer 1

I assume you already tried to reinstall the application and I would recommend to do it one more time, but this time follow the process for so-called manual uninstall
1. Uninstall Crystal reports 9 using add remove programs
2. Save backup -up of the Registry
3. Remove the following registry key (be careful with the registry file):
HKEY_CURRENT_USER\Software\Business Objects\Suite 12.0\Crystal Reports
4. Reinstall Crystal Reports 9
As the next step I would check and disable Data Execution Prevention.
Go to: Start> Right-click My Computer" select Properties> Advanced tab > click Performance settings> Data Execution Prevention tab.
If DEP turned on for all programs, then add Crystal Reports (crw32.exe) to except list.
If DEP is not cause of problems, then I would suggest Process Monitor to locate the reason or at least try to locate it.
You can download Process Monitor utility from the following page:
http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx
The same page will tell you how to use it. I would suggest the following steps:
Close all unnecessary applications/processes
1. Open Crystal Reports
2. Start the Process Monitor, stop capturing events (Cntrl-E), clean the display (Cntrl-X), add the following filter (Cntrl-L) "Process Name is crw32.exe then include", click ok.
3. Start capturing events (Cntrl-E)
4. Immediately click Format menu on Crystal Reports
5. Stop capturing events and save the log file
Now you can look at the log file to see what is going wrong. I would also advice to capture the same log on client machine to compare the sequence of events.
