Problem with keydecoder.dll in Crystal Reports 2008 Trial Version

Question

Hello,
My company is interested in purchasing Crystal Reports 2008 and has asked me to download and try the trial version.  However, I have been running into a keydecoder.dll problem.  Setup was smooth and here are the details:
Problem message:
"Crystal Reports: Application Error Couldn't load keydecoder.dll"
I have Windows Vista and I have already configured all permissions and administrative rights to the problem to full control.  I have also attempted to drag the keydecoder.dll application extension out of win32_x86 to the file folder crystal reports 2008.  I have also already attempted to reinstall and making a new program file location named 'Crystal Reports 2008'. 
I'm running out of ideas and would appreciate some help.  Thank you

For your reference have a look to content of that Note:-

Symptom
When attempting to start Crystal Reports XI, the following error message appears:
"Crystal Reports: Application Error - Couldn't load the keydecoder.dll".
Cause :
The error message occurs because the CommonFiles entry has the wrong path in the registry.
Resolution :
CAUTION The following resolution involves editing the registry. Using the Registry Editor incorrectly can cause serious problems that may require you to reinstall the Microsoft Windows operating system. Use the Registry Editor at your own risk. It is strongly recommended that you make a backup copy of the registry files before you edit the registry. For information on how to edit the registry key, view the 'Changing Keys And Values' online Help topic in the Registry Editor (Regedit.exe).
To resolve the error message
Click Start > Run. The Run dialog box appears.
Type "regedit" in the Open: text field. Click OK. The Registry Editor appears.
Navigate to the following key: HKEY_LOCLAL_MACHINESOFTWAREBusiness ObjectsSuite 11.5Crystal Reports.
Double-click the CommonFiles string. The Edit String dialog box appears.
Ensure that the path points to the location of <installation directory>Common3.5 in.
For example, the default location is the following: C:Program FilesBusiness ObjectsCommon3.5 in.
Edit the path as necessary.
Click OK. Close the Registry Editor.
Crystal Reports starts successfully.
Hope that helps!!
