I'm trying to add a custom report format to ssrs 2005 as per this
https://msdn.microsoft.com/en-us/library/ms156281(v=sql.90).aspx
I've added the code snippets in the example to three different ssrs 2005 server RSReportServer.config files but it does not work i.e do not show up in the export drop down when rendering report. I've tried starting and stopping reporting services and it still does not works. I've also modified the existing csv extension with different options to see if it works but to no avail.
However it works with SSRS2008 R2 . In fact it works right after I saved the config file, no restart needed.
For SSRS2005 the file is in C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportServer. I checked the registry setting just to make sure I'm looking at the correct installation 'HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\ClientSetup', 'SQLPath'
The three ssrs2005 instances are in three different physical servers and the problem is with all of them so it is not an isolated incident. I've dbowner rights to all three servers. The server versions are 9.0.4060, 9.0.4035 and 9.0.4053
