Hello,
We are experiencing a problem with our WinForms application that uses the ReportViewer 14.0.0.0 to generate local reports.
This issue is sporadic and most users report that if they try to run the report 3-4 time they can finally get it to work.
I did some reasearch and found an article (link below) that said that report Viewer creates some Dynamic DLL's and some virus scan programs don't allow that and cause a problem. We have entered an exception for our virus scan program (Symantec) to
ignore files in the c:\users\<username>\appdata\Local directory but users are still reporting the issue. The error desribed in the article isn't identical to mine but it sounds like exactly the same behavior.

Below is what we see randomly when trying to run any of our reports
an error occured during local report processing
The definition of the report xxxxxx is invalid
An unexpected error occured in report processing
Cannot execute a program. the command being executed was "c:\windws\microsoft .net\framework64\v4.0.030319\vbc.exe" /noconfig @"C:\users\<user>\appdata\local\temp\mi0w1ktv.cmdline
Any help is greatly appreciated. this has been happening for several months and I have exhausted all of my resources trying to figure out what is wrong.
we recently moved to symantec as our Virus protection, our windows 10 computers constantly getting updates, and I recently upgraded to version 14 of Reportviewer if any of that makes a difference.
