Standard Export to Excel Problem in NAV 2013 R2 (Build 7.10.37221) Cumulative Update 9

Hello All,

one of our client is using NAV 2013 R2 (Build 7.10.37221) Cumulative Update 9.

when I try to do standard export to excel in any List page of NAV it shows below error & client is crashed.

Microsoft Dynamics NAV

---

The server "DynamicsNAV71" was unable to process the request. Close the application and start it again.

---

OK

when I check with Page type "Worksheet" it works fine, even in reports there is no Issue to export to excel.

Please help.

Thanks,
Ravi Shah
