The definition of the report is invalid [solved]
hello all, we have a report on our SQL 2019 Reporting Server that works fine. when my colleague downloads the report and redeploys it, he gets an error The definition of the report is invalid Google says: Check Changes and Schema. There is no wrong Schema
http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition The solution was: The report uses qrcode that needs *dlls. We have installed two dll locally on the computer and then the deploy also works on the other computer copy *.dll to c:\windows\system32 (as Administator) run Developer command Prompt as Administrator gacutil -i qrcoder.dll gacutil -i EncryptDecrypt.dll now it works fine
