Solution 2: Update the Export DLL Files
Another possible solution is to update the export DLL files to the latest version. You can download the patch for Crystal Reports from [SAP website] and extract the ZIP file. Then, replace the existing export DLL files in your computer with the new ones. The export DLL files are usually located in one of these folders:
C:\Program Files\Common Files\Business Objects\3.0\bin
C:\Program Files\Common Files\Crystal Decisions\2.5\bin
C:\Program Files (x86)\Common Files\Business Objects\3.0\bin
C:\Program Files (x86)\Common Files\Crystal Decisions\2.5\bin
After replacing the files, register them using the regsvr32 command in the command prompt. For example:
```html regsvr32 "C:\Program Files\Common Files\Business Objects\3.0\bin\ExportModeller.dll"
``` Repeat this for all the export DLL files that you have updated. Then, restart your computer and try to export your report again.
Solution 3: Add the Export DLL Folder to the PATH Environment Variable
Sometimes, Crystal Reports may not be able to find the export DLL files because they are not included in the PATH environment variable. The PATH environment variable is a system variable that tells Windows where to look for executable files, such as DLL files. To add the export DLL folder to the PATH environment variable, follow these steps:
Right-click on My Computer and select Properties.
Click on Advanced System Settings and then click on Environment Variables.
In the System Variables section, find the variable named PATH and select it.
Click on Edit and then append a semicolon (;) followed by the path of the export DLL folder at the end of the existing value. For example:
```html C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Program Files\Common Files\Business Objects\3.0\bin
``` Click on OK to save the changes and close all the windows.
Restart your computer and try to export your report again.
Solution 4: Disable Antivirus or Firewall Software
In some cases, antivirus or firewall software may block or interfere with the export DLL files, causing the error "No Export DLLs Found" in Crystal Reports. To check if this is the case, you can temporarily disable your antivirus or firewall software and try to export your report again. If the error is gone, then you need to add an exception or a rule for the export DLL files in your antivirus or firewall settings. Refer to the documentation of your antivirus or firewall software for more details on how to do this.
