Try to rename folder STAAD.Pro CONNECT Edition into STAAD.Pro CONNECT Edition _1 in the folder C:\Users\User_Name\AppData\Local\Bentley\Engineering\. If that does not help, try to reinstall STAAD.Pro by running the installer as administrator. Also, make sure that STAAD.Pro version 22,01,00,39 is being used.
Thankyou Sir now the problem is resolved.
But Why this problem occur???
