I want to install crystal reports 8.5 on my windows 11 but it's not registering craxddrt.dll

To resolve the issue with registering craxddrt.dll for Crystal Reports 8.5 on Windows 11, you can try the following steps:

1. Run Command Prompt as Administrator: Ensure you are running the Command Prompt with administrative privileges. Right-click on the Command Prompt icon and select "Run as administrator".
2. Register the DLL: Use the following command to register the craxddrt.dll file:

      regsvr32.exe "C:\Program Files\Common Files\Business Objects\2.7\Bin\craxddrt.dll"
   

   Make sure the path is correct based on where Crystal Reports is installed on your system.
3. Check for Errors: If you receive an error message, it may indicate that the DLL is not a valid ActiveX component or that there are permission issues. Ensure that you have the correct version of the DLL and that it is not corrupted.
4. Modify Access Control List (ACL): If the registration fails due to access issues, you may need to modify the ACL for the DLL file. To do this, follow these steps:
   • Open Command Prompt as Administrator.
   • Document the current ACLs for the DLL:

          cacls "C:\Program Files\Common Files\Business Objects\2.7\Bin\craxddrt.dll"
     

   • Deny access to the "Everyone" group:

          cacls "C:\Program Files\Common Files\Business Objects\2.7\Bin\craxddrt.dll" /E /D Everyone
     

   • After making this change, try registering the DLL again.
5. Check Compatibility: Since Crystal Reports 8.5 is an older application, ensure that it is compatible with Windows 11. You may need to run the installer in compatibility mode for an earlier version of Windows.

If these steps do not resolve the issue, consider checking with the vendor for updated components or additional support.

Dear Khawaja Shams

Unfortunately, Crystal Reports 8.5 is a very old 32-bit product (released in 2000) and is not officially supported on modern operating systems such as Windows 11, which leads to issues like failing to register craxddrt.dll. In most cases, the DLL registration fails because Crystal 8.5 relies on legacy COM components and older system dependencies that no longer exist in current Windows builds. One workaround you can try is manually registering the DLL using an elevated 32-bit regsvr32 command: C:\Windows\SysWOW64\regsvr32.exe craxddrt.dll However, even if this succeeds, other components of the designer may still not function properly on Windows 11.

The most reliable approach is to run Crystal Reports 8.5 inside a Windows XP or Windows 7 virtual machine and develop your VB6 project there, as this environment fully supports the older runtime. Many customers use Hyper-V or VMware Workstation for this purpose with good results. Alternatively, upgrading to a supported version of Crystal Reports (such as CR 2020) is an option, but it may require changes to your VB6 application.

I hope this information is useful.. If it is, don't forget to "Accept the answer" so that it could be spread further to those in need too.
