I have some Crystal Reports (V10) in an application (.NET 1.1) I inherited that is deployed in four \"identical\" environments. In three of the environments, they are workin
I recently experienced this very issue: although my resolution was a little different:
Once I went into the C:\Program Files\Common Files\Crystal Decisions\2.5\crystalreportviewers10 folder and turned off custom errors I could see the error was coming from an access denied issue on C:\Windows\Temp\
The solution was then to not and handlers or alter IIS to run scripts and executables, it was to allow the Network Service to read permission on C:\Windows\Temp\
EDIT: Think I've found another solution which doesn't require permission changes... just set a virtual directory for aspnet_client; the level at which you select this will very much depend on your IIS layout.
