We upgraded our sistem from SQLExpress to SQLServer2008R2 and now we have problems in report deployment.
We tried with VS2008, reportbuilder and also with reportManager.
On Reportbuilder the error is:
Errore imprevisto durante l'elaborazione del report. ---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: Errore imprevisto durante l'elaborazione del report. ---> System.UnauthorizedAccessException: Access to the path 'c:\Temp\expression_host_deb45de35c4b4c0ca92c6887dd8123c2.dll' is denied.
on Report Manager the error is:
Errore imprevisto durante l'elaborazione del report. (rsInternalError)---> Access to the path 'c:\Temp\expression_host_1ca689557e1849f1924030a683dcda15.dll' is denied.
The reportserver service account is a server Administrator and a sysem administrator on reporting
We granted full controll to Everyone to c:\temp folder
We can deploy without problems datasource
With ReportBuilder 3 we ca deploy without problems Report Part, but when we try to publish the report we have the error.
We can deploy without problem new report.
How can we solve?
