Hi - I have been running Win 8.1, VS Studio Ultimate 2012 and CR Reports SP4 quite happily now for a year or more. My app has a VB.net front end which modifies Select and Sort strings before running 1 of 52 reports in the Viewer. The database used was Access jet, which sadly has just been upgraded to Ace (Access 2007 +). I used the modify database location to change the .dbf to .accdb and this worked quite happily for 49 of the 52 reports. The 3 reports which failed all had sub reports.
When trying to run the failing reports these I now get the message. 'Not implemented. Error in file temp_............rpt: Operation not yet implemented.
I have upgraded the environment to SP12 - it fails, same error message.
If I try to run the report in CR2011 it works just fine, including sub-report.
If I remove the sub-report it works fine.
If I remove the sub-report and add any sub-report from scratch it fails - same error message.
Any help will be well received, I've no idea how to even try to move forward.
BTW this is a commercial app.
